On this specifically, I'm doubtful. The 'backdoor' isn't very high value. In many other cases technology transfer, joint management/ownership, market access, political favors, lucrative contracts, direct infiltration, nationalist instincts, and bribery are all reasons for Microsoft to work with the NSA and other intelligence agencies. They were caught providing backdoor access along with Google to all outlook (and gmail) emails to the FBI, for example.
