Fair enough, I amend my statement. It's censorship in the sense that things are censored, i.e., *deliberately* prevented from being shown or communicated based on their informational content.
I just don't find those things to be in the same category as a government arresting protestors, for example,
Correct; that is government censorship. There is not, however, a qualitative difference between Twitch deciding to ban one behavior from being depicted over another, whether it be gambling, nudity, racism, or people doing that trick with their spit where they let it stretch down several inches and suck it back into their mouths.
I'm not seeing a real "point of view" being expressed here, which IMO is also an important part of censorship.
Well your opinion disagrees with the dictionary. I don't know what to tell you.
