And what has been the impact been of Trump's ban? He's still perfectly capable of getting his message out. His followers are perfectly willing to move to non-mainstream sites like Parler and Gab, and they're still all over the mainstream sites to boot. He's still the overwhelming favorite for the GOP in 2024, and he's starting a social media platform and possibly a streaming TV deal. Trump simply not being President anymore has had a bigger chilling effect than being deplatformed.
As always, the right's hatred of the left has led them to overplay their hand. It's obvious to everyone that neither Trump nor his supporters are oppressed, suppressed or censored in any meaningful way, and certainly not to the degree that they claim.
Well, I'm not a Trump supporter, and have no horses in the left/right race- however, it seems obvious to me that there is censorship involved, given Trump is literally banned from those platforms. Anecdata- the only time I ever saw anything Trump had to say was on Twitter, and since his banning, he might as well not exist in my own infosphere. It's amazing to watch the pretzels people tie themselves in trying to justify their ideology.
