At least Firefox tells you that they collect data from you and leads you to the configurations for enabling or disabling it, and if you disable, you trully disable telemetry.
Microsoft lies, and tries to hide the privacy settings (at least akng it complicated to acess for average users) in several places, and even if you can turn that off, the OS still sends telemetry information, which you need to disable via registry settings, and even then, they still send data to Microsoft, then they cover their backs with their "on the law" terms and conditions. It' sthe same corp that said "Users need to be re-educated to know what they want" when Windows 8 was a total fail for PC users... Not to mention all those updates that bricked systems or made endless reboot loops... Imagining that on a system that hides the abiity to disable automatic updates it's a nightmare. MS demonstrates it cannot be trusted blindly, which is sad; I grew up with MS OSes, this makes me sad...
After Windows 7, MS has been doing nothing but fails, Windows 8 it's a fail with that stupid mobile stuff over PCs, Windows 10 now it's a fail because of abusive corporative practices... Users now are being fooled, do you like to be fooled? I do not, and I bet neither you...
Why MS... why are you betraying the users that have been with you since the beggining? Money? There is something over that... value, Windows is quickly loosing it for power users...
This is the reason people is ranting about this politics, is not about collecting data per se (which, while being done by others like google, which happen to give you switches to turn that off completely), but about trying to fool, hide information and treating you like a dork that doesn't know about PCs...
Jut my two cents...
