Bring back the forums, flickr, good old chatrooms and the DIY web as alternatives. Reject anything that mandates your real ID. Reject any attempts by politicians in your respective countries to copy this kind of stuff, that includes laws "against fake news and spread of disinformation/hate speech", a trojan horse used to identify political adversaries using anonymous accounts; I'll keep on insulting them online and troll with friends whenever they come up with stuff like that.
