That's not censorship problems.

That's advertisement problems. That's conflicts of interest problems. That's incentives problems. That's people-who-post-videos-just-to-make-money problems.

Well, okay, it can easily be turned into censorship problems: instead of just demonetizing the video, don't show it to anyone. It's quite a fine line, but the line is indeed there.
