My guess is that some "policy" person/team needs to report they "removed xyz apps violating ToS per week" as their quality bar, so they actively seek any reason for banning an app. It's the same reason why companies dumb down their UI, make weird "unique" choices or remove useful functionality, because some team needs to report work.
