The gruberment must have some deal with Microsoft to get ALL the peasants on Windows 10, so they can be monitored 24/7/365.
The deal, such as it was ( think Godfather, an offer they could not refuse ) probably occurred between fall 2004 and spring 2005 when the Longhorn ( eventually released as Vista ) beta code had a dramatic alteration after a long period of frozen stasis.
Folks on the outside speculated that it was 9/11 related but did not get any firm evidence until a couple years ago when Microsoft was confirmed as having been the first and primary PRISM partner with NoSuchAgency. Allegedly they signed up in 2007, but that in itself may be a smokescreen and is close enough to the Longhorn/Vista fiasco to be significant.
It should be noted that Hollywood approved DRM ( protected content path ) was infamously introduced in Vista and almost sunk the product from the outcry. Their willingness to bend over for the Hollywood mafia demonstrated just how fast they would drop trow and bend over for FedGov, especially if the agencies approaching them were draped in the flag of 9/11 and anti-terrorism.
Of course this also means that all the other companies likely did the exact same thing eventually. Anyone who distrusts the entire industry is not without merit, even if they get accused of tinfoil or whatever. Almost everything they feared has already happened.
And it continues on. I mean, if someone set out to design a new way to check everything at will, where the sheeple march to them, they might just come up with a fabulous concept and call it a cloud, or facebook ...
