What I'm saying is that this is a survivor effect: there are plenty of cases where deplatforming
does work, it's just not 100% effective and so we have this situation like antibiotic resistance where pathologies have evolved around the defenses. It's kind of incredible that viruses have managed to evolve around vaccines to install a pro-virus person at the top of the US department of health to ensure better spread of viruses, but I guess life finds a way.
Also: this is entirely anglocentric. I don't think you'd find anyone claiming that the Chinese government censorship system backfired or is completely ineffective. It's an even stronger system than billionaires over there.
