I think the solution is to ban the "algorithm" that determines your feed. People sign up for posts and photos from friends and family and groups, instead that is held hostage and released as a trickle with ads and fake endorsements (your friends like brandX) and targeted stories chosen to trigger emotions and go viral.

The feed should go back to being RSS essentially, that's what people really expect out of fb/instagram.

Also, just like government sets limits on roadside advertising, online advertising should be limited (area-wise or frequency), with clear distinction and attribution for all ads. In addition, there should be limits to profiling such that ads can't be shown to less than 10K viewers for example.
