This should be renamed to "I let my users do the testing".
And what a great philosophy. Just don't apply for jobs in aviation, or anywhere critical.

Meaning that, over the past century, there was actually a ton of "testing in prod" in aviation. The industry learned many, many valuable lessons only after the billions and billions of hours of flight time exposed issues that weren't caught in preflight testing.
GP would like aviation users ("passengers") to not be the ones doing the testing. You state aviation users historically tested -- it's why flight regulations and rules are written in blood. I suspect the blood of passengers is exactly what the GP would like to avoid.
I can't tell if you didn't make the connection, or if your commenting style is just to naturally start negatively. My suspicion is the former, given the throwaway account.
the more "failed tests" in production, the safer aviation becomes.
we give thanks to those who have fallen (literally, out of the sky).
You’re deluding yourself if you think the aviation industry just sells directly to customers new aircraft without testing them.
“Testing in prod” means, “I’m gonna try this thing and I’m not sure if it will work and my test environments don’t cover that so I’ll go straight to prod and see if it breaks.”
The software industry is the only place where that works because shipping to prod is literally faster than test suites in lots of cases and the stakes are so low on failure.
Unexpected catastrophic failures in prod != testing in prod.
Because the article very clearly says that you should still test before going to prod, but that it's just as important to treat going to prod as another testing stage where you will find problems you couldn't find before - and that you need to be prepared for that so you can find them early.
Doing so is very much an important best practice in aviation - you monitor planes in production, and you try to make sure that problems which almost lead to disaster are reported and investigated, rather than hidden.
