You asked for suggestions that didn't involve outrage and I gave you some.
These are suggestion that have been around for a long time and even Jack Dorsey from Twitter and Tim Cook from Apple have bought it up recently.
Facebook's creates hundreds of unintended consequences. The suggestions I mentioned just addressed two specific issues - addiction and the spread of ignorance/fakenews/bad info (nuclear chain reactions require control rods same with viral info). Especially dangerous in countries where most of the population is too illeterate to counter it.
Look up Tristan Harris former Googler humanetech website and you will find many more human thought and behaviour effecting dark patterns that social media sites use that need to be addressed.
Ideally we need a bug tracker for social issues being generated in the same way we track software issues.
One example of a big problem without a fix that would be at the top of the list is having 14 year olds exposed to the most viral and extreme problems of 35 year olds day in and day out is leading to higher anxiety/depression in kids. The EU, Canada and UK have data out on this.
The suggestion for these kind of issues is, mandating such a "bug tracker" increases awareness. The regulations are being worked on.
