The personalised feeds is the whole point of their reason of being. No personalisation no profits. There just isn't a world where these huge companies can exist without personalised feeds. Meta platforms as well as YT would die and you would have instead something like Nebula which you pay for like Netflix but offers content creators content. Most people wouldn't pay for Nebula and so, you are back to the original point. People would put pressure to restore personalised feeds. Everyone supports these bans until they are the target of them.

This isn't a technological problem but a human one. The fundamental problem is that we haven't developed generalisable, scalable and profitable business models on the internet that aren't toxic.

Not true. YouTube, Facebook and Twitter were all successful products before they added personalised algorithmic feeds. Facebook just showed you everything by your friends. Twitter showed your follows (like bsky) and YouTube showed your channels.

The personalised algorithmic junk came later. It was never required for the websites to be wildly popular.

The tech isn’t that expensive or complex. Email didn’t have to add all this junk to be sustainable.

Something like the original Facebook where it’s just posts from your direct friends and no public content would be sustainable. It just wouldn’t make a trillion dollar company.
