On the one hand, this could be heavily abused by an authoritarian government to censor online discourse
On the other hand, there needs to be more serious consequences and incentives for these platforms to proactively manage this stuff.
On the third hand sprouting out my chest and flipping off the first hand; all these platforms are already willingly and eagerly censoring and shaping online discourse to favor authoritarian governments, largely by way of refusing to be proactive about such things and allowing them and their goons to go without any real oversight. This is probably going to do more to stop authoritarian demagogues from coming to power than it could ever be abused by them once in power.
