As a microsoft employee there are some topics that legally I can't talk about. It's not that I don't have own personal opinions, but rather that something I could say could be represented as Microsoft's policy or legal opinion.
I'm not a lawyer, I'm a developer, so even tho I've had a ton of internal legal training, I'm not comfortable speaking about the DOJ, or any of the legal matters that surround Microsoft's business practices.
I bet Rory has a similar view and besides talking about the intricate legalies on Channel9 would make me leave the site.....I'd much rather see videos and discussions about technologies....don't you??
