I understand this is somewhat my privilege speaking here, but I don't think I could continue working at a company that didn't do something as basic as hashing passwords (and refused to prioritize fixing that as soon as I pointed it out). It's a massive ethical, if not legal (IANAL), liability -- and a huge breach of users' trust. It's 2021, hashing user passwords is astonishingly easy; I can't imagine any remotely justifiable excuse for something like that.
