ISP enforced requirement to sign in (give your real name) before using the internet. Every post you make, every torrent you download, is attached to your name.
The vast majority of traffic concentrated in a few hands (Google for search, Facebook for communication, Amazon for shopping, etc). Personal sites, blogs and forums almost nonexistent. Already heading in that direction.
All traffic decrypted and analyzed for "suspicious" patterns on the fly. Already happens with cloudflare, but will be done by ISPs.
Automatic censorship, done by AI. Blocking all information related to conspiracies, alternative news, and such.
Buying access to websites, like with TV channels. And unblockable ads on top of that.
