This is a never ending story that continues to repeat itself. New ideas and development are almost always done with good intentions. That idea then gets manipulated and misused, normally by government, government agencies and military.
If you don't like the new policies, I'd look closer at your government than I would Microsoft. I'm not saying corporations are not guilty, but they are generally after your money more than your intellect. The government wants the latter.
Just like ISP's are forced to log all data and provide access to it, that move is now being made to computers in general... why - because the technology has opened that door. Have you ever been startled by Googles ads... the ones that show you EXACTLY what you were looking at earlier in the day.
That's not evil, that's targeted marketing. BUT - that same information put in the wrong hands can do a lot of harm.
Those that think staying on Windows 7 or 8 will be safer is fooling themselves. The user agreement can be changed at any time, with any update. If this is something that really concerns you, the only choice you really have is to unplug your machines from the internet. OK - keep one machine online for basic communication and Netflix.
