Who owns my computer?
Half-hidden under many of the comments here are serious questions of ownership. I don't dispute that Microsoft are entitled to operate any business model they please, and that if I am foolish enough to buy their products I will be bound by their draconian EULAs. Including paying subscriptions for what increasingly looks like ransomware.
However, the computer I am posting from is mine. I did not buy it with Windows already installed - I built it myself. The machine, and any data held on it are mine, and I regard my data as private - not a resource to be mined for someone else's marketing campaign. I do not, and will not, consent to MS trawling through it, though that is what the (Win 10) EULA claims to authorise them to do.
It is MY damn PC, which is why it runs Linux Mint 17.
