It's shocking for many reasons that Joyent thinks its reasonable to fire an employee over something as trivial as that pull rejection.

Not correct him first, but fire him.

Not stand behind him, as in "sometimes we all make errors", but fire him.

This is callous, abusive, shocking behavior.

Is it a lack of training and sensitivity on the part of Joyent, or their fear of retaliation from the Tech Feminism?

This statement of Joyent's should be condemned by anyone who has ever held down a job.
