Here's what I've seen when the powers-that-be disrupt online communities... most people who were "casuals" stop paying attention when the convenient options (Twitter, Parler) disappear, and just go on with their life, watching Netflix or football instead. But the truly hardcore get pushed underground into a smaller and more virulent community (which Parler was to Twitter, and which something will be to Parler).

I expect Trumpism to take a hit as a political movement but thrive as an extremist movement as a consequence of this "shunning." Expect fewer 2016 elections and more January 6th terrorism.
