I can respect that private corporations have the right to "censor" (I put that in quotes because nowadays literally any moderator action is considered censorship) while disagreeing with specific decisions by corporations to do so. I wouldn't say newspapers shouldn't endorse candidates if they endorsed Trump (as some papers have done,) but I would think that was a bad idea given Trump's animosity towards the press.

I can also distinguish between the value of the press and the value of a social media platform. Banning an account on Twitter doesn't carry the same social weight as banning journalists. To me, while both are legal and within the bounds of free speech, one is distinctly worse for society than the other.
