>there is more restriction than ever of the distribution of information

I don't think it sounds true. Pre-internet, information distribution required access to specific technical tools, and physical transportation efforts. As one of USSR dissidents noted, risks of distribution grew almost exponentially with amount of pages (and it's about imprisonment, not account deletion). For comparison, emailing so far works even in very repressive countries. And even narrowing the issue to the West, while free speech suffered a lot recently, shadowbanned account is probably still works better than hectograph.
