It absolutely is their fault. They did not need to immediately capitulate to censorship demands by the payment processors. They *could* have fought for us and for freedom of expression, but they didn't. Don't give complacency a pass.
I'm not gonna pretend that i know how this works, but i don't think they could do anything. Maybe they could, i have no idea. They could be doing a lot more, for sure, but i wouldn't blame them that hard.
