Big tech censorship reignites call for an Internet Bill of Rights

Are there examples of this "censorship" available? I'm under the impression that "censorship" is something of a red herring.

Last month, I took a good look at Qanon twitter, and my opinion was that those folks are mainly having technical or conceptual difficulties when they claim "shadow bans" or whatever. A lot of folks haven't done the arithmetic about how many people they follow, rate to tweets and how many tweets they read in a day, otherwise they'd realize you can't possibly see everything all your follows put out.

It would be totally weird to have technically uninformed people dictate that, say, the CAP theorem be violated to protect their free speech rights.
