The entire situation is ridiculous, but Mitchel's response probably won't go over well with his employer.
<time to get some popcorn and watch what happens>
I work at microsoft and honestly the Mitchel guy seems unhinged. I saw him posting every 15 minutes on our internal Yammer today about this. He ranted a lot about how people at HR plotted against him in the past. Honestly his autism might get him fired because he took it way too far.
