Yeah, I managed a major service back in the day and I can confirm all you say is absolutely correct (except maybe #3, but that's legal).

One thing I do not understand however is why wouldn't companies offer paid appeal process perhaps with refund in case the termination decision is indeed overturned. I would gladly pay $100 to have my Apple/Google/etc account properly reviewed in order to get it back once it is inevitably flagged by yet another AI. Seems like win-win all around.
