I don’t see how would it be a double-edged sword. It’s a meme, but we do in fact live in a society, with laws made mostly democratically by people (ideally) — which is the closest thing at this scale to a fair system. Why should a private company get to decide what it wants over the local laws? If it were to host child porn, should we be okay with that even though we collectively have voted to ban any form of pornography of minors?
