Microsoft Releases .Net Framework Source ... and Receives Criticism

So if you're up on Microsoft or .Net, you've probably heard by now that Microsoft is going to release the source to the .Net Framework. I see this as a positive step and think it can only help .Net developers not just support, but understand what they're working with. Anyone curious enough about .Net has been decompiling .Net source via Reflector for quite a while now (I know I have).
