I agree with the sentiment, and I do have a blog (of which I'm the only visitor as I don't advertise it).
However... for me, the communities come first. I mean I do have a goal in my internet usage, and this goal comes before any principled stands (mostly; there are exceptions). So if, for example, the hobby communities around games and crafts I enjoy form in Facebook, what can I do? Facebook sucks as a platform, but I want to be in those communities because I enjoy being part of them. It's a trap, but one where there's no easy way out.
As for YouTube: my search history and the algorithm are my main use of YT; I wouldn't dream of turning them off. Because I basically use it for two things, my hobby things (subscribed to several channels I like) and watching cartoon clips with my daughter, all the algorithm ever recommends me is exactly those two things: cartoon clips and things related to my hobbies. Never rage bait, never random nonsense. When I click accidentally on rage bait inducing stuff, I remove it from my watch history; I know this isn't perfect but it works in the sense I don't get recommended that crap.
Also, YouTube Premium because I can't stand ads. Yes, I'm aware I'm paying the mafia thugs to leave me alone. It sucks.
This is no defense of YouTube, I know it can turn to shit any minute, but at least for me the algorithm works.
The one thing that is absolutely driving me nuts is the AI-driven en-slopification of the internet. I wish AI got magically banned from most venues. I want to interact with humans and human-created stuff, not AI spam. I think this is a battle that cannot be won, to my eternal sadness.
Again I must repeat I do agree with the sentiment of the blog post, and I wish the internet got de-enshitified again. I'm not sure it's that easy though.
