The blog post reads somewhat honest, at least the part where he says he is just a nerdy programmer.

The end however is a bit weird considering he didn't sell it for the symbolic sum of a single dollar.
Then again with 2.5 billion he can now do and try and program whatever he wants I guess, so he basically took the financial freedom offered to him and I can't honestly say that I would have said no to that.

And I still don't think Microsoft is inherently evil.
