I think fixing popular "mistakes" like this is problematic in its own way. Google/YouTube approach the problem of moderation by using unreliable systems and correcting mistakes when there is enough of a popular outrage. The problem is, people who can't generate the outrage are subject to Google's poor moderation.
If Google did not fix mistakes that generated a lot of outrage, then competitors could differentiate themselves by providing better moderation policies and whenever some popular account got banned from YouTube that would generate a lot of traffic for alternatives. As is, if something popular gets banned, YouTube will "correct" their error while they ignore things below this threshold. This simultaneously subjects everyone to their poor moderation and stifles an advantage that competitors might enjoy.
