Why can't it be fixed? Just remove algorithms and show only subscribed content in chronological order. That's how most of the early platforms worked and it was fine.
And what would be the downside of that? :D
This is also how Mastodon works today, and it is fine.
I left FB around the time of Snowden leaks. And watched the others all go the same way. I only use them judiciously now for specific information. Even YouTube i have history off so I don't see a recommendations page and I just check my subs semi regularly.
So yeah. The web is better and less stressful that way. New generation perhaps doesn't even know it.
