Because in order for freedom of speech you also need freedom for people to say dumb and abhorrent things. There are some clear bad things like hate speech, and Grey things like Covid conspiracies, maybe they should be banned, but removal of w11 bypasses sends a clear message that google is the lapdog for other big businesses.
and it is why total freedom of speech on a platform does not mean we can trust it. maybe even the opposite because people who tell a lie are more motivated (money or whatever)
I am not justifying w11 video removal I'm just saying thinking youtube trustworthy because it's open to everybody is a mistake
