YouTube is a content delivery platform that has social media features. You can tell because if you shut off all the comments, people still visit the site in droves. But if you shut off the videos and left the comments then nobody would visit the site at all.

Now, it's possible that YouTube doesn't realize that, but I think they're just unwilling to make any changes at all if it doesn't give them any competitive advantages.

Well I've always had history turned off, and a few years ago YT blanked out the home screen if you have history turned off. Ever since then I have a blank home screen with just a message saying to go into settings to correct the error that I have history turned off.

I never used to subscribe to any channels, but then when they blanked out the home screen you have no other way to get any kind of feed. So only after they did that, I subscribed to a bunch of channels so that at least the subscriptions page would have some kind of feed.

This still doesn't give you anything related, just exactly the subscribed channels. If you want any kind of variety and quantity you have to keep subscribing to more and more channels so that the subscriptions page can almost sorta provide something like the old home page before they blanked it.

I complain, but I gotta say one thing, this way I NEVER see Mr.Beast or SsssniperWolf or anything like those any more. So, maybe it's better this way.
