Although some of the jokes are inevitably tasteless, and Zorrilla is used to set up punchlines, I enjoyed it and it will surely increase concerns and donations for shrimp. I'm not sure what impression the audience will have of EA in general.
Last week The Daily Show interviewed Rutger Bregman about his new book Moral Ambition (which includes a profile of Zorrilla and SWP).
I think that a huge chunk of charity is pretty thoughtless, and that many viewers in absolute terms would have felt some sympathy for shrimps, even though they're speciesist. Most donors also like splitting across different problems out of some sense of fairness. Putting these together, I can easily see many non-EA viewers donating to SWP soon out of guilt, at least as a once-off. The segment ended on the website link in huge font, and I think that was a significant prompt.
