While I'm not sure that's what they do they DID get caught red-handed a couple of years ago snooping on urls sent over Skype.

"route everything through government surveillance" is perhaps a bit too blunt, but let's not forget that Microsoft was the founding member of the PRISM program.

And Prism or no Prism-- Skype was a $1bn present from Microsoft to the intelligence community. Even if they never snooped on anything (we know they have) they did re-engineer skype in a manner that allows it to be subject to more traditional CALEA trap and trace techniques, as well a numerous side channel attacks and traffic interception. The "secret sauce" of Skype in the very beginning was P2P connections, which MSFT immediately removed.

Isn't skype still P2P?? otherwise why would it have an option to disallow P2P between you and people you don't know?

I don't know if I would characterize what they were doing as snooping. Is Google snooping when GMail does a keyword scan of your email? IIRC, Microsoft was loading the URL to look for malware.
