The world is so different place in unsafe countries, people might be playing with their lives(and lives of their close ones) for doing this stuff. It's not unlikely for a totalitarian government to assassinate opposition, to physically kill activists. You say that's wrong, but I ask whatcha gonna do about it?
Sure, and this is most probably an expected possibility, but also the only way to operate safely. Exposing your name and your political stance along with activism can get you killed.
Of course the reliance on US based(of all Western countries) company through which all the stuff gets organized and through which the communications happen might have to be questioned -- but the status quo is that there are no viable alternatives and it's very unlikely to change due to the nature of the market.
