I agree and those reasons you listed are why I don't have any issue parting ways with this platform, but I don't think the general public does. People do use instagram and tiktok to view what I (and I'm guessing you do too) consider noise.
And after all, the general public is who views the ads on their site and brings in the money.
As someone who spends time curating the content I view without any care given to what other people enjoy, I'm often shocked at how terrible the content on something like youtube's front page is when I get logged out. It's easy to forget that a lot of people just don't care and use the internet to turn off their brain.
