So far, the big platforms seem to be digging the hole of censorship deeper, and small platforms like Parler are deplatformed.
Unless we find a way to circumvent the tight control that smartphone manufacturers have over devices they sell, the only possible haven of free speech would be web on a Windows PC with some specific browsers. Because Google adding you to a list of dirty webs means that people using Chrome won't get to your website.
We've seen revolutions before and they were not pretty.
Society will run away from this and the pendulum will swing again toward Morton Downy Jr., The Man Show, Politically Incorrect, 101 Ways TO Kill A Cat, Jerry Springer, etc.
The big platforms will quietly acquiesce to the public's "new found" acceptance of the risqué.
Deplatforming is an extreme measure when they perceive an existential threat like "abetting an insurrection."
Some users are bound to replay real-world conflicts there. Israelis and Palestinians will scream at each other, Europeans will draw Muhammad cartoons, Rs and Ds will love each other unconditionally as usual... and all this attention sells ads, but also creates uncomfortable side effects.
Political outrage drives engagement much more than cute cats.
AWS pulled the plug on Parler a few days after the Capitol riot, and then justified it with evidence of posts from before the riot. If the riot had not happened, then surely Parler would still be hosted on AWS today.
So the big players are not proactively censoring anything; it's all engagement metrics, then CYA when shit hits the fan. But take heart: that means that small platforms really can live under the radar.
Nobody is going to pull that particular plug.
