Why would big tech ever want to get rid of nasty meat bags when nasty meat bags drive much of their engagement and thus increase their advertising revenues? We can't escape the realities of how the human brain operates, how much it likes to be stimulated regardless of the qualities of the stimulus.

I think a much more logical goal would be to take just enough action to avoid most (but not all) legal consequences while otherwise encouraging as many nasty meat bags to encounter other nasty meat bags with opposing viewpoints as possible. That would maximize brain stimulation, increasing engagement and thus revenue. This improves the stock price and makes your boss happier with you.
