> this sort of thing shouldn’t be possible any more than a bank deciding to take all your money with no recourse. (They can close your account, but they can’t keep your money.)

I once had to help a relative sue a bank who had closed his account after he refused to answer their very intrusive questions (they wanted to know details about distant relatives living in another country). They also refused to return his money (tens of thousands) and refused to explain why. No amount of complaining or escalating made any difference, although we did manage to get a nice recording of an employee saying that he thought the bank was in the wrong.

It took me issuing court proceedings, plus several more months of negotiating with their lawyer, before they finally settled out of court. Even then they tried to not pay the court fee, and they tried to get us to sign an NDA (I refused to budge on both). Altogether, it took 6 months to get the money.

Similar to how people in this thread are talking about mitigating reliance on cloud providers (e.g. with offline backups), I now do not trust any bank. I avoid being in a position where any one bank can ruin my life. That means having multiple accounts and spreading my money around.

Luckily for me I have a legal background so when a corp (big or small) does this sort of thing to me I don't hesitate to sue them. In almost all cases this causes them to "wake up" and start taking your issue seriously, in a way that the front line customer support reps never do. I recommend this to the author of the original post.
