It's a tricky problem. I think tech people are fringe. For me, I would want to disable it all. But if people can turn it off then it doesn't let microsoft improve and adapt. In concept, I kind of like the idea the OS could anticipate the things I need. It's how we imagine futuristic computer systems. It's a bit different from the traditional OS where you are the master over everything.
I'm not sure many on HN are going to like this thing, but I would think MS gets to see the stats and has better view of how well they are doing. Percentage wise it might be working out pretty good, however, each percentage point they piss off ends up being a lot of people and if the fringe of tech people are in that 1% that can end up in a lot of angry blogs.
