RSS feeds broken, player broken, buffering broken, idiotic ads if you don't uBlock Origin the hell out of it ... I think the only thing they didn't yet ruin-bloat is content, because that's created by other people, but those people are also producing tons of trash and AI generated crap, so content is also broken. It is up to the visitor to filter out trash and find the few good contents amidst all the rubble. If today a competitor managed to gain significant amount of quality content and the ability to also deliver that content, YouTube would pretty soon be out of business, I think.
