Apparently Microsoft works for Microsoft in a mob like way. In true mobster fashion, he is open about his work but follows the "I work for Microsoft" statement by saying that he can't actually tell people he works for Microsoft. Sounds a little shady to me.
This guy, much like Sammy Gravano, couldn't stick to the mob rules of speaking nothing of what you know and not speaking about things that should not be spoken. Both are rats... Unfortunately, for Gravano, he is wasting away in prison with a thyroid disorder and multiple convictions. Fortunately, for Microsoft, I'm pretty sure he was lying about working for Microsoft, not breaking the sacred covenant he claimed to have made with Microsoft regarding the secrecy of his supposed employment.
I know I openly profess to have a thing for nerds, but seriously, let's not make things up. And if you feel the need to make something up, go with astrophysics. It's a heck of a lot sexier than Microsoft.
