In a way I see these algorithms as segregstionist, their goal is ultimately to isolate certain groups and perniciously expose them only to the rage inducing bad aspects of the other group(s) to generate more posts/likes/comment.

Segregation applied to public spaces should indeed be banned, when these platforms become so huge, they become a defacto public square that you can hardly avoid effectively without missing a good share of the conversations that need to happen in public for a healthy flow of information, so I would not see an issue with law makers to regulate this... obviously as long as it's applied fairly.

The issue is that currently even platforms that are getting regulate, for even more concerning aspect (national security, undue foreign influence on fair elections) like Tiktok seem to be exempt of the law itself and the US Congress seem unable to get the laws they voted in a bipartisan manner enforced... the only reason I see is that a certain tangerine tinted individual sees it as a tool to control the American discourse in his favor, and thus refuses to enforce the law. So these concerns about healthy public spaces are taking the backseat for now.
