The ridiculousness of this defence makes it clear leadership was in the know.

https://kolejowyportal.pl/koleje-dolnoslaskie-odpowiadaja-ne... - this is from 2022-07-06. The train owner complains that they still didn't receive information from Newagg about what was fixed when unit had to be shipped to manufacturer after it refused to start.
So the issues with 3rd party servicing were publicly known well before the smoking gun was found in firmware.
IIRC, there was some "konami" code to re-enable the train after disablement that was removed in a first-party update after the third-party repair company found the sequence.
And not related to the third-party locations, one of the trains had some code where if the year>2021 & month>11 & day>? then the train would disable itself; ultimately doing it in the wrong year because the train was off during november / december of that year. This is a little excessive for somebody random to do.
