It is all data slurping
Wondering why "telemetry" has become synonymous with "surveillance"?
To the average user both mean that data from their machine is being sent somewhere.
Because Microsoft has not revealed what data is in their so called 'telemetry' messages it is easy to see why people think rightly or wrongly they are being spied on by Redmond.
Then because you can't turn it off without going through a huge number of hoops that impression is reinforced 1000%.
I do not use Windows 10 any more. W10 was the last straw for me. After six months of fighting with it (Windows 7 is a pussycat in comparison) the nannying approach that MS has adopted won the day and I deserted to Linux and MacOS.
I have one Server 2008 system that is only connected to the Internet 2-3 times a year. I think it will be ok for a while longer as the applications it runs don't need to be connected or phone home every few minutes to check on their licensing status. When that hardware dies that's it for me with MS.
Keep on mollycoddling your user base MS, I'm sure that when you introduce subsctiptions it will make you Billions but at what cost eh?
