I take it you’ve never done any serious software development.
No matter how much they try, the in-house testing environment will never be as diverse as the “wild”. Running the software in production, where it will encounter a vastly greater range of system configurations, and users who will report issues, is often the only way to catch the more elusive bugs. Like xz. And let me point it out because people seem to have completely missed it: they caught the bug and fixed it.



That’s pretty much what happened. Windows 8 was such dogshit that it might be indirectly responsible for the revolution of Linux gaming. https://archive.ph/iHl8q
