Yea, that's probably fair. I didn't mean to suggest there's no scope for improvement or investment. But I suspect that you and I differ on our estimates of the degree to which this is possible, particularly without fundamentally changing the platforms and drastically reducing their value for legitimate usage.

The existence of the gap also doesn't change the fact that my experience is that implicit in the majority of the mainstream conversation about these topics is is an imagining of tech giants as wielders of unlimited power over their billions of users, and I'm skeptical that they'd be satisfied with most/any of the points in the valley you describe.

Not to mention that the flipside of public opinion is that the caprices of an algorithm are even more hated than their cases of leniency! All of the suggestions you make are going to increase false positives, and the PR backlash I've seen from that is far worse than the backlash to unmoderated content.

That isn't to say that there isn't room for reasonable complaint, but most people are really, really stupid, and even worse, entirely unconcerned with the consistency of their objections (a problem exacerbated by the fact that different vocal subgroups complain about different problems, and our various media will happily signal-boost all of them). Again, I don't see a solution that threads the needle effectively other than blunt restrictions, leaving everyone worse off but neutering the worst of the PR damage.
