"Independent", Satire right?!
Haven't you heard of PRISM? or 'patriot act'?
The biggest concerned, i believe, most people have with censorship is that "they censor and at the same time claim to be a 'platform' not 'publishers'".
It would be 'ok', if they say who they 'are', not pretend to be open and at the same time silence voices who they disagree with by pretending to 'fact check'. 'Fact check' what? Peoples conversations? For what reason? Then it should, at least, be voluntary. You see the concern people have, right?!
