Oh my does this ever bring traumatic memories!
This entire article reminds me of a previous company I used to work for. There was a sufficiently large number of engineers that had a similar, if not more elaborate, deliberate, and sinister way of responding to bugs:
* Deny {bug} is a problem - "I don't see how this affects you/anyone?"
* Deny {bug} can even be fixed - "Ok, fair, but I don't see how this can be fixed?"
* Deny {bug} is their problem - "Ok, fair, but have you tried asking {other employee?}, they are responsible for this." (they are obviously not)
* Be rude - "If you think this is a problem, then go fix it"
All this was just obvious defensive walls of lies to protect their reputation and hide their lack of skill and their laziness.
Around 5% of the engineers were like this and I've always analogized it to the proportion of U238 in a sample of Uranium - just enough enriched dogshit to cause a critical mass of misery.
I left (for greener pastures) shortly after I had a couple of tasks requiring interaction with these "engineers", which made working around them impossible, and then realizing that leadership had totally lost control of the zoo and didn't care one iota.
