You're making judgements on people's utility and ability based on the volatile reactions of man who admits to having issues. That creates toxic environments where people are not encouraged to do better, but any amount of change is due to fear of repercussions. This does not promote growth or new ideas that would genuinely improve something, but rather a fear of failure if they attempt something new. This also isn't useful programming criticism because the actual useful criticism is buried in an emotional slurry that's going to make something less receptive to the useful information.
