I think they need to balance how strict their abuse detection is. Making it too strict will kick out legitimate users without mercy. Making it less strict will allow potentially harmful (for business) content to spread on their platform, which could lead to lawsuits, loss of advertisers etc. You can see which direction is more appealing for a corporation.
So concretely, now we complain about mistreated users, but if the automatic moderation was less strict, we'd complain about extreme content. It's not an easy problem.
