You're talking editorializing, not censorship. Legally they can be whatever they want to be, they're private business after all, and largely unregulated. The question is if they should keep certain advantageous legal protections if they become editors, and that's certainly debatable.
Even the notion that they're editorializing is debatable and would have to be tested in court, as they don't actually modify the user's content. That would be an interesting case.
Sorry you have trouble with words like ambivalent. Look them up, you have internet after all.
It would cost me absolutely nothing to tell you that I agree or disagree with the measure they've taken, but I'm being honest here, and I think about the pro and cons of this quite a bit. We're not anymore at a time where somebody would publish some slander on a newspaper, and then they could be sued for libel, and go through that whole process.
Instead now we have a million things going on at any given time, everybody thinks they're a journo, and there's both a ton of bull flying around and plenty of customers for it. This is also largely why I don't consume it.
So this is quite a new terrain, and I'm not sure what I have such a firm position on this as I did in the past.
I used to be much more pro-information-disclosure, I admit to that. I also think these things eventually become public and known anyways (this one did regardless of what social media did or did not do). Same fate awaits the much less redacted Mueller report, for example.
