None of what you wrote is a response to what I said, beside “well, if it gets bad enough, society will adapt”.
You admit that in the current market, those companies are vastly important in a way that can’t change quickly and their acting as censors could turn so bad, it would force a change to the very way we communicate.
I think “hellish” is an apt description of “would reshape hundreds of billions to trillions of dollars of economic activity in response to the social disfunction it caused”.
