Cant imagine what such a disgusting feature will do to system performance, I mean yes, M$ are geniuses in making malicious tech transparent, but there is only so much they can do. In win10, you can almost feel being spied on with every single mouse click you do, the ever present subtle lag, you can actually feel it. Its not present on old versions of 7 & vista.
My theory here is the Govermint were worried this new tech would interfere with and expose their transparent methods of spying on and controlling the masses, they said, you have to make sure its not going to destabilize that facet of society, sure, you can milk them for every cent you can, but you must do so in a "legal" way that doesn't risk destabilizing the way we control them or take their rights away. You must make sure their data never gets intercepted by anyone on its way to 3rd part corps and nefarious gov agencies.
