YouTube has no problem banning content on ideological grounds, though. I remember last year various news articles about YouTube's removal of white supremacist content.

I don't really see why it's important to distinguish whether the content is problematic "factually" vs "ideologically". Clearly there are valid reasons to ban content on ideological grounds but on the other hand removing any content that has factual errors would be cumbersome (or impossible) to do. You need to also look at other criteria to make a reasonable determination.
