The Wytham Abbey Project is closing. After input from the Abbey’s major donors, the EV board took a decision to sell the property. This project’s runway will run out at the end of April. After this time, the project will cease operations, and EV UK will oversee the sale of the property. The Wytham Abbey team have been good custodians of the venue during the time they ran this project, and EV UK will continue to look after this property as we prepare to sell. The proceeds of the sale, after the cost of sale is covered, will be allocated to high-impact charities.
[Edit: 3rd May] Since this announcement, we have decided that we will use some of the proceeds on Effective Venture's general costs. I consider EV to be a high-impact charity.
A statement from the Wytham Project can be found here.
The Wytham project doesn't fundraise from anyone now (having decided to shut down); the rationale for releasing at least some of the requested information is to evaluate EVF, which did and does solicit public donations. Its board was intimately involved with the controversial Wytham grant in the first place, and likely the decision to shut down a project also was ultimately a board-level decision. (There are also reasons for non-donors to want to evaluate EVF, given its leadership role in the ecosystem.)
This does push us a bit back toward the Apple Watch example. But I think entities with a tub-based structure will ordinary experience both significantly lower costs and risks to releasing more detailed information. Almost by definition, the tub-based model requires a more significant degree of internal accounting than a joint-pot model. While that may be of little significance for one of the world's largest companies, I think the extent to which added transparency would require incurring additional costs / cause diversion is pretty relevant when we have small-to-midsize nonprofits in mind.
Also, Apple faces a risk of divulging competitively valuable information -- e.g., how much it thinks watch R&D is worth investing in, line items for specific research projects, etc. And divulging competitively valuable information is antithetical to the main reason (shareholder interests) for Apple's existence which is also related to why one might expect more detailed disclosure in the first case. It's not clear what the analogous risk to a tub-based (or really any) nonprofit in terms of its reason for existence (i.e., the public interest).
