I'm not seeing what's troubling here. Going strictly off of the examples you provided, I see that they largely hold their donations as bonds, while re-donating the rest to either purchase open source software or, at the government level, prevent tech companies from selling privacy or participating in censorship. As an anarchist, wouldn't that be something you'd approve of?

I don't use Firefox. I find the UI to be clunky. But after reading your examples I'm persuaded to switch.
