Censorship, beyond what’s required by law, is doomed to fail.
So you can lose credibility two ways, one by not doing any censorship because people on the internet will be the worst if you let them. Doing too much censorship is also bad because people don't like that either. Of the big causes of censorship currently, I think of things like youtubes copyright claim process and how that is routinely used as a censorship backdoor by anyone - including the police. Sometimes its not even for any good reason and done by unthinking bots. This is banning more perfectly fine content than anything the government has done. I don't understand why there isn't more pushback against that process to punish people for frivolous claims.
If you look at every attempt to create "The Uncensored Free Speech Version Of [ANY_SERVICE]," they all, inevitably turned into a 4chan-like trashfire. You've got to have some kind of moderation.
So whats changed?
Well, I have my thoughts, but one thing is for sure, as soon as the platform itself tried to start moderating, that's when things really started changing.
Kicking people off was and still is censorship and moderation. Services really try hard to not kick people off now and just police the content instead.
On top of all of this, bans were frequently appealed and overturned.
> Every message board and chatroom (bbs, forums, irc, icq, aol, et all) on the young internet was virtually uncensored and a 100% free for all
But if your definition of "virtually uncensored" is that there are uncensored instances, then IRC, forums, etc. are just as "uncensored" as ever. There's just a lot more internet users on moderated platforms now.
Also Facebook, MySpace, Twitter, et all all started off pretty uncensored and unmoderated to build the moats. Then they started cracking down once the feds and political influences kicked in.
