Just off the top of my head: 1) what specific mechanisms are used to hook people initially? 2) What specific mechanisms sustain or deepen the addiction? 3) What actual value do the provide to users? 4) Who specifically do they harm, and by how much? 5) Who uses them without harm? 6) What societal impacts, positive and negative, do they have? And I could keep going, but you get the idea. Any one of those could be a hundred research projects. Even if your sole goal was to regulate them out of existence, you'd need a lot more than "I think Facebook is bad". You'd at least need a solid enough definition of the problem to craft the ban in such a way that it stuck. But that's a very unlikely outcome, so most of the people working on this are looking to minimize harm while maximizing value, and that just requires a lot of detailed research. For example, compare Facebook vs Mastodon, or vs HN. Do we ban them all, because "social networks bad"?
