Turning a process/culture that works 99% of the time into 99.99% is often surprisingly expensive. For example currently as a company you may have some slightly less attentive engineers or less strict code review process for convenience and speed, or you may pursue lots of projects with tight deadlines etc. which can lead to a situation like this with non negligible chance, but usually won't. Most of the software you use doesn't routinely delete user data, it's an accident. To avoid it you need to hire higher quality engineers or more of them to give them breathing room and less workload, and have to give up on some new features and innovation, which is really not so easy in a competitive market.
