If a social media owner routinely goes around removing things they disapprove of, it makes sense to assume that they approve of the things that are still up and thus safe harbor shouldn't apply.

Also I was talking more about bigger social media like Twitter, Facebook etc. Most fedi instances are more in the territory of "hey friends, come hang around at my house"
