Think you have to deal with the world as it is, rather than as it should be, if you want to make progress.
I’ve always found accepting that ego thing to be very difficult as I’m quite happy for people to scrap my ideas if they’re bad, but a lot of people aren’t wired like I am and I don’t hold that against them. Could be a genetic thing. I have other faults that they don’t, so tolerance is needed in both directions. Humans are buggy.
If you want to make progress you change the world as it is to the way it should be and throw out notions like thinking people are 'wired' in certain ways to rationalize the status quo.
These bug issues or bad software practices are results of a culture, and work cultures can be fixed. Hence OPs example of experiencing a very different culture in another country, and presumably German's aren't genetically built different to respond better to software error reports.
And the best time to fix it is right now because it'll be more expensive in a year.
