My stance is... if they use 6gb of my internet to download updates... okay, whatever... i get unlimited(ish). But if I turn it off and it still does it... that sounds more like a bug in their software. It's still not a big enough deal for me not go with Windows for an OS... it's too good of an OS. I don't think it warrants boycotting MS.
P.S. I didn't pay for Win10. They gave me the upgrade for free.
