Unpleaseant experience and all, but sounds like complaining about not reading the full terms and then being shocked after the first bill, which is ok if you are buying a personal service, but that's a no-no in business.
The argument of "like many early startup do, we oversaw this and ignored that" doesn't really make it better.
Most countries have consumer protection laws, but they're only for consumers, due to the usual power imbalance. Power is expected to be balanced in B2B transactions - your lawyers spent as much time ensuring you weren't scammed as theirs spent trying to scam you - so there's no protection law about that. You get whatever the contract says you get.
Kinda sounds like the post I replied to was ok with companies scamming or using dark patterns on consumers. Even if they're better protected it's not like it's perfect.
