That episode of Community also explicitly referred to the black face as a "hate crime." I don't think it's so much a matter of interpretation as that was the direct gag they were going for.

Do we know who actually pulled the content? Netflix clearly doesn't have a policy against streaming partial amount of content when they can't get it all from a provider but it's not clear to me if Netflix pulled a single episode of Community or if the licensers maybe refused to license that episode. I think I read that Sony was supportive of the episode being pulled.

I think most of this content will come back once the industry as a whole sort of figures out the positioning. There are something the creators are embarrassed by and it might never come back but I expect there to be a new rating or something similar (Disney+ does this already) where they'll indicate before the media plays that it may be offensive or insensitive. News shows do this when covering certain types of crimes.
