What's worse is that the few in control of TOR refuse to update their threat model (which is almost 20 years old) and implement solutions for this. I guess their Navy bosses want to keep access for "the good guys inc".
I am unsure what TOR developers can do to with twitter/facebook/instagram. The platforms business model is to collect personal information in order to sell advertisements, and blocking people who they can't identify is a business decision.
Tor could create their own society network but that will do nothing for people who need to reach people on those platforms.
