Nothing new
I think a lot of people seem to forget that Microsoft have been collecting and using telemetry data since at least Windows Vista, this is nothing new here.
Organisations have always had the option to disable this via Group Policy and with Windows 10 consumers can rightly turn these options off from the get go.
This is just another case of the tech journalists blowing things out of proportion again without properly doing their research first.
FYI 1511 is the version number of the Windows 10 November update not the build number. 10586 is the build number.
