That is censorship. Prior to this point in time only hate speech, inciteful, vulgar, things were censored. To remove speech from the view of others that is contrary to your own simply because you believe it is "garbage" is censorship. Perhaps the other side believes your speech should be censored. Let's have your comment removed because of your generalization of speech you don't like as "garbage" doesn't conform with the guidelines i just thought of right now and actually, i think your comment is "garbage". How to punish you for your opinion now? 12 hours ban? 24? Deplatformed? Where does it end? THAT is censorship.
Stop using someone else's services for your expression. Just imagine you are in Walmart or a Target or your local grocery store. You don't have a right to be there or to engage in any speech or really anything else if the manager wants you removed from private property. If you want to nationalize Twitter and Facebook be my guest but until then the owners of said private property can continue to kick people off of it. I still have yet to see one case where a person's right to free speech were somehow infringed upon.
I would put forth that you're not going to get far in this conversation if you can't acknowledge that censorship and government abridgement of free speech are not one and the same.
A company deplatforming an individual is indeed censorship, but is not government abridgement of free speech.
