How do you know EPIC isn’t for sale? They don’t disclose who their donors are.

They're a 501(c)3, they take donations off the front page of their website. Sure, you might be curious who is donating? Or if there are any donations over a certain amount? I don't see any of that for The March of Dimes, either, do we question whether they are "for sale?"
I think it's reasonable to ask some number of questions about the March of Dimes. It's surprising, at least a little bit, that eradicating polio didn't reduce the amount of charitable work a polio charity had to do.
The EFF, popular with many tech workers, also falls into the latter group. They've started to pivot post all the privacy scandals of the past few years, but in general they've taken positions that align with the tech industry. There's a reason why they've been preoccupied with government surveillance but have been silent (until recently) about corporate surveillance.
