This might be an unpopular opinion but I always thought we might be better off without Web 2.0 where site owners aren’t held responsible for user content
If you’re hosting content, why shouldn’t you be responsible, because your business model is impossible if you’re held to account for what’s happening on your premises?
Without safe harbor, people might have to jump through the hoops of buying their own domain name, and hosting content themselves, would that be so bad?
What about webmail, IM, or any other sort of web-hosted communication? Do you honestly think it would be better if Google were responsible for whatever content gets sent to a gmail address?
You know this site would not be possible without those protections, right?
Any app allowing any communication between two users would be illegal.
