> "What do we do about it?"

I'd suggest something like banning algorithmic amplification - your feed is posts of people you follow and nothing else. But that's not what will happen. What will happen is there will be [1] vague laws about preventing vague "harm", written to give legal teeth to the Overton window. Not in those words, but companies that would go against it will be mired in lawfare, while those that comply will be allowed to grow.

And if you complain, they'll motte-and-bailey you - you're not in favor of "harm", are you? We're not an authoritarian speech police, we only seek to protect people from "harm".
