This basically boils down to: it's okay to inflict damage upon customers that don't make you money. That is not only unethical, it should be illegal. There is no way for a customer to know beforehand that this will happen to them, and at the sheer scale these companies operate, voting with your feet is impossible. The reason is that 99% of customers will never run into a problem, but the 1% that does gets damaged disproportionately without repercussion.
