Not bitter at all, not sure where you got that impression from my post. If I have something that does not present me in my best light, why should I volunteer to show it in a hiring process? I am just being practical.

I do think all hiring processes have a component of arbitrariness, so I don’t think it is necessarily a bad sign that a company quickly dismiss candidates from poorly-maintained GitHub accounts. I would gladly not show my GitHub and try to get the job showing my skills in some other way.
