The "bankrupt your company with the wrong keystroke" is not entirely accurate. AWS does work with companies (or even individuals) if they genuinely made an error that wracked up a huge bill. Personally they have dropped bills of $1000's when I made a bone headed mistake and have seen companies get $100 000's of bills credited due to the same issue. They are not in the business of ripping people off in the short time who would spend a lot more than that in the long term.
