to be honest it still doesn't bother me that he copied a few lines of code
It was never a few line of code. There were (multiple) entire significant modules that were identified as refactored (i.e. copied and reformatted). This does
not mean that other parts were not also copied, it just means that no one went to trouble to compare and identify all of the copied code. Why should we do his work for him? It is his job to
cite the copied portions, no matter how much or how many, not hide them.
Why re-write DirectX or OpenGl? Game devs use it all the time.
That's because the licenses allow it and if you look in the copyright notices for just about any game you will see the required attributions and license notices for the redistributable code. Game devs who use redistributable components don't claim to be geniuses who implemented them from scratch.
Now I agree his CHARACTER of not attributing that or admitting it is the problem. But still I say this all has nothing to do with the code it has everything to do with the man's honesty, character, and psych issues.
I actually don't care about his personal problems and I actually wish people would leave him (or other people with personal challenges who pop up here from time to time) alone about it. There is a sadistic streak on this forum that comes out where certain people want to "beat up the special kids" whenever they can. It isn't admirable.
Whatever challenges john-conner faces I hope he gets the help he needs and/or otherwise manages to reach some state of happiness and peace in his life.
