From just a basic reading of the Windows Universal Apps description, all UAs report analytics data back to Microsoft which routes to the developer. I expected that, store apps already do it. What was really cringe-worthy was reading the Get A Developers License which carries monitoring into your system. Even should you have a non-internet connected machine (you get issued your license from your domain admin), it seems you still agree to some form of local monitoring as it will revoke your license on the spot, without a connection. Okaaay!
Definitely not letting this beast near my machines. VM, obvious, even though that fails to test the most important aspect here: H/W compatibility.
