I really don't think you're understanding how this works. Using extant power structures to suppress discourse is a terrible thing only when the wrong people do it. See also, everyone in this thread coming up with reasons that they don't care that he was suspended from twitter.
what extant power structures? Owners of a brand repeatedly told this apparent garbage dumpster that he was in violation of their terms and in their opinion (aren't corporations great?) not representing their brand properly.
So ignoring their warning, they banned him.
I don't see any violation of any rights. I see him blatantly violating the terms of their service as they explained to him.
So the fuck what?
If you don't like it then don't use Twitter. Encourage your friends not to use Twitter. boycott them. Start your own Conservatwitter (as previously suggested in this thread).
You have options, because this is a free country and it is functioning remarkably well despite many delusions to the contrary.
Oh, Twitter, is, by virtue of its current popularity, an intrinsic part of society and an embedded information resource that should be protected under some specific constitutional amendment
that has never restricted any news media from ever controlling the nature of its own content? That is quite the precedent that you are claiming.
Are you sure that the chili stain on your "pocket constitution" isn't obscuring some important parts of the 1st Amendment?
