Be careful of confirmation bias and the availability heuristic. One irresponsible person does not define the masses.

It absolutely is something they would normally run into. I work on maintaining a massive application; think 60+ teams of 6, each extremely specialized and minimal overlap. Almost 75% of my job is predicting issues and avoiding them. Peer testing draws on this a ton as well. They just continue to plainly show that they don’t care. Time and time again, year after year, they continue to have the exact same issues and do fuck all about it.
