So while Apple has taken steps to eliminate the ability of an app to access any sort of unique ID connected to the user, Microsoft is going full steam ahead with this? And adding this to Windows 10 on PCs - when they are already getting paid good money for the OS?
At least Google has a valid reason for pushing this stuff on people, because they make nothing from Android aside from the advertising revenue. Microsoft wants it on both ends, payment up front and continuing to sell your eyeballs down the road, and bringing it to PCs to boot!
Glad I use Linux and iOS!
