The main negative I have is just the opposite: YT’s algorithm persistently pushing crazy alien theories, Joe Rogan and Jordan Peterson garbage into my feed, or worse. I wish they would censor that stuff more, because I’m not interested and no matter how many times I say “not interested”, it finds its way back in.
I either get "<Ideogogue> destroys <ideology>" videos or some really insane things, my favorite being videos from instructors who say they can teach you to fly if you give them thousands of dollars. By fly, they mean levitation and not airplanes.
To clarify, I don't consider YT's algorithmic choices to be "censorship" one way or another. Censorship is blocking, banning and/or demonetizing videos and preventing consumers from proactively deciding what they want to watch. I fully agree that allowing users to curate what Youtube suggests to them would be a massive improvement over the current system. If you are interested in learning more about actual Youtube censorship, Matt Taibi has been covering the issue for almost 2 years.
