Historically speaking, it has been incredibly rare for subs to be taken over like that. Subs have run with rules about banning members with at least 1 comment in subs they don't like (usually the_donald, mra, conservative, etc) [banning over non-sub behavior is a big no no for a long time with the admins], there are subs that aggressively automod, there are subs that ban over constructive criticism, there are subs where active mods are pushed out at any moment by a top mod, etc. Heck, there are a few subs that require photo evidence of your race or gender to participate. Unless it highly embarrassed the company or it is an ongoing violation of their content policy, mostly those communities still remain as they are.
