So you mean the change in their model (some years back) from P2P to via-their-servers?

Having ZERO trust to Microsoft's ethics, and with the dark history of leaving things unpatched for 3-letter agencies to go berserk, it makes that theory semi-valid. I am sure that Microsoft will neither xobrifm, nor deny this allegation ;)

Edit: every time I see something massive breaking in the news about system vulnerabilities that existed 2-5-10 years, it makes me think that NSA/CIA/USA lost control of the tool/vulnerability, and they run to patch before other state agents get the chance to equally abuse that.
