Except to their own companies bottom line, generating millions in revenue? Releasing less often is a way to guarantee that bigger bugs will get through at some point, requiring hotfixes etc. The more you release, the higher quality releases you have, and the smaller production incidents. The point isn't to remove QA, it's to trust that the automation in place is high quality and will catch the majority of issues before they are issues (i.e. if something makes it through the automation, then it should be caught in the internal release, or at least the 3% canary group), and then on the back of issues, make the automation more robust. The more people who are introduced into a process, the more likely it is to fail at some point - the fact is that Facebook has a pretty low rate of huge production issues compared to most software companies, they must be doing something right.
