You & upstream ("Imilcim") are both right, but both your examples are flawed (Android is not really Linux, MCAS is a logical design flaw). Linux can be very stable (most of the time it is). I think that in this context "Quality Assurance" (QA) is king, independently from what it tests. Linux has a lot of stuff included in the kernel, and that stuff is actively used by a lot of people in a lot of different (potentially unexpected) ways => if QA can certify both custom-written-SW and Linux (for the needed usage) I would then tend to trust Linux more than a SW written by dedicated teams in companies (because of the possibility that QA could miss some tests which might have been indirectly caught by the Linux community/users).
