If a ToS is going to be a contract, it has to be interpretable by the person hitting 'agree', no? If someone is confused about what it means and reaches out to the company and they respond by
locking the user out of their account which they use to generate their livelihood, it has stopped being an 'oopsie' and become a 'we don't care about our customers, we only care what they give us and will use strangely worded legalese and extortion to get it'.
The response of 'why would they ever assume bad intention by a startup tech company which pivoted recently to focus on AI offerings' crocodile tears just makes it worse.
At this point, barring the existence of an impeccable and long-running reputation, if you assume that any place you store your data is not going to screw you the moment they can to make a buck, then you are hopelessly naive.
