The big problem with Twitter and Facebook is they have massive incentive to encourage lightning fast viral content. But there are big societal problems with viral content which contains lies and incites violence (or voter harassment, etc). So now they are trying to blame the individual sources which is effective to some extent except when the sources are hugely popular with certain segments of society. IMO the real solution is to massively slow all viral content's spread. That of course would damage the platforms, particularly if their competitors don't implement similar limits. So all the platforms are playing this kind of cat-and-mouse game and doing a piecemeal approach fraught with ethical and potential legal issues.
