After a ~5min online research on Emerson Spartz's past CEO role at his previous company "Dose", it looks like there were a lot more "disgruntled ex-employee[s]" (even if this is external to EA). 

Overall, CEO approval is at 0%.  Some examples out of the many:

•  Terrible, Toxic, Traumatizing, Environment I actually consulted lawyers about a potential retaliation lawsuit after my experience working at this sicko company. 4 years later, I still have nightmares. Like, actual nightmares while I'm asleep. There are some seriously manipulative, narcissists at Dose. If you are a semi-decent person who cares even an inkling about your own well being or the well being of others, I highly suggest staying away from this insane company.
• Yikes. Working at Dose is like being in a sorority who thinks they're really cool, popular and making a difference in the world, but are so blinded by their own delusions and egos, that it couldn't be further from the truth. Specifically, I'm talking specifically about upper management. The "leaders" not only have no clue what they're doing, but they refuse to listen to other people's opinions and play favorites. If you're not extroverted or as "hyped" about the company, you’ll become less respected. Those who can speak their language of BS buzzwords with enthusiasm are those who get promotions, get invited to happy hours, etc.
• Stepping Stone Job Toxic workplace, with little to no career pathway. Inexperienced management.
• Toxic:Truly the only way to succeed at dose is to suck up to upper management, as your growth there will depend more on how well you manage to befriend the higher ups than your actual work ethic. Beware: lack of training, constant gaslighting, putting people on the spot [...] are the norm. Dose acts like it's fun and cool but there is a reason why half the team quit [...]. Also, there is rampant nepotism at dose, with the CEO hiring many of his friends that aren't actually competent (and you can't really say anything because they are friends and there is NO HR - big red flag). I could go on, but in general, upper management at dose is stuck in a high school mean girl attitude and it seems that will never change. if you're looking to 1up your career, use them for a period of time and then get out. Otherwise, run far far away. The managers put on an amazing front of being friendly and will tell you things like oh your mental health is important etc etc so you think it's this amazing place, but it's really not.
• Progressive Company? No amount of snacks make up for the toxic and traumatizing workplace environment nurtured here. The leadership micromanaged, gaslit and blamed everything and everyone but themselves while team members quit one after the other and the remaining unrealistic workload fell on fewer and fewer shoulders. The expectation was that working “just” 40 hours a week wasn’t enough. On any given week in the office, the chances were pretty high that someone would end up crying, screaming or melting down. All this from a company that once called itself “progressive.” Also, from a diversity perspective, look out if you are a person of color. The sometimes “subtle” and often explicit racism and prejudice I witnessed had real impacts on many careers, kept promising candidates away and sent talented professionals to the door. Everyone was aware this was happening and nothing was done. This is not a progressive company and I don't think it's an ethical one. Maybe things have changed. I hope they will. Advice to Management: Try kindness, trust people and believe what they tell you. do something
• A discouraging place to work Toxic work environment -Lack of infrastructure -Burnout galore. Witnessed employees having crying breakdowns at least half a dozen times due to the pressure and workload. -Unpaid overtime -Tight deadlines for a high volume of work -Too many cooks in the kitchen/top-heavy upper management/everyone wants to feel important -No matter how hard you work or how much you accomplish, unless you're willing to consistently be on call past working hours, your work is seen as lacking, or, at best, on par. -The other reviews say it all. The goalposts are always changing, workflow is chaotic, and everyone is overworked. Advice to Management:  Stop taking miles when your employees offer inches. When you're a decade-old company, the "we're a scrappy startup" line comes off as a glib excuse to treat your employees like workhorses. Deliver when you say you care about your employees' well-being by creating actionable solutions instead of just doing damage control and trying to placate them when things get especially bad. Hire more people, especially creatives, to handle the workload or stop overpromising to clients.
• Values their clients more than their employees Toxic culture - Expected to work overtime without extra pay - Our mistakes are called out constantly, but our hard work is rarely acknowledged - Management often changes the organizational structure/goals of the company, which results in disorganization and more stress. - Creatives (designers and copywriters) are not being heard by upper management. No matter what the client asks for, management says yes without even thinking about the capabilities or bandwidth of their creative team. This often results in creatives spending an unnecessary amount of hours bending over backwards to execute something. - At least half of the company has had one foot out the door for the past 6 months. There is nobody here who enjoys this company. - Don't work here unless you want to be belittled, stretched too thin, and undervalued. Advice to Management: It's not enough to just say "I hear you" when your employees are expressing their concerns. Stop telling them to "be agile." Listen to them, believe that they know what they're talking about, and learn how to push back to your clients when necessary. Your employees are exhausted and unhappy. Get it together.

There are many more negative and honestly very sad comments on Glassdoor. 

Given the time it took me to look this up, I wonder if background checks are ever being done at EA in the first place (specifically when multi-b/millionaires such as SBF and Emerson feel the urge to embellish their reputation by suddenly becoming "highly caring altruists" without having displayed any signs of altruism before).  Highly wealthy people could simply be treated like new hires at regular companies because they have a lot more power and are more likely to have different intentions than the average EA.

Doing quick background checks is a very low-cost and reasonable thing to do in order to protect  EA  and its members.  

The problem with people like Emerson S. is that they come with a lot of private resources, enabling organizations like Nonlinear to pop up, rise and survive out of nowhere. They never had to gain the trust or follow standards like everyone else had to - they can just self-fund.

 They're not subject to the same scrutiny as others. 

This is even worse, given that they learned how to get so far/accumulate so much wealth in the first place: they know how to behave strategically to get what they want. 

I am truly sorry for anyone who has had to endure such management practices inside and outside of EA. I hope that background checks will be normalized to avoid such problems in the future.

I’m surprised and sad to hear you now think that way about our past experience. The last time you reached out to me you were overwhelmingly positive towards me. Let me know if you’d like to talk about this more. 

On a minor note, I felt important to say about the quote: we didn't claim there was only one disgruntled ex-employee. In fact, the next sentence says: "While this person, no doubt, wasn’t the only disgruntled ex-employee".

What is the evidence for manipulating voting scores? Feel free to say you can't share, but if it can be publicly evidenced in some way, as it seems it might, that would be more informative.

If you think someone is breaking the Forum's rules, I encourage you to contact the moderation team. 

If something seems sketchy but doesn't clearly break any rules, you should still reach out. The situation might lead to a rule change, or at least alert moderators to pay more attention to threads involving specific users.

FWIW, I don't love nonspecific allegations like this — it's nigh-impossible for Nonlinear to respond to them, and serves as a cheap or free way to make others think worse of them at no cost to yourself. By contrast, the initial comment at least gave enough information that Nonlinear could respond to some of the claims.

What you did was valuable, useful and brave.

With difficulty, trying to communicate in a way that gets at the heart of the issue and not pick out facts and tries to be fair: 

My guess (50% true/certain) is that it's probably fair to say that Kat and Emerson have a bit of a hustle vibe (I mean look at Emerson's description).

Like I would do, and you would do, they try to maximize their local success. However, their output hasn't been extremely high. There might be a small departure from some EA cooperate norms, that might be due cultural differences.

With the greatest uncertainty, but the most importance?: I think the potentially major issue is that by trying to sit as a meta org, Nonlinear can attract inflows of EA talent that scales with the movement (and not their ability), and also self-replicate. That is bad for movement health and incentives. EA is also small enough (and the course has seen a negative trajectory) that this could be an issue, e.g. the lemons sit in the aftermath, there's a path dependency. The communication/publicity maximization adds to this concern.

As this thread shows, they are unpopular enough at this point, that I think the concerns are probably minor, like top #30-50 item on the list of things that CEA or OP needs to worry about in the next year or two.
