Kind of late to the party on this one, but honestly I don't find it to be a huge concern. The options are easy to turn off, and most of them seem to be either advertising-based (and as annoying as ads are, they do pay the bills for many content creators) or based on tweaking the Windows 10 experience for every user. I turned a good bit of mine off, including Cortana because I didn't see the point, but it doesn't seem to be as big a deal as people are making it out to be. Now, if Microsoft hid the options to turn them off, that'd be one thing, but when turning them off takes 5 minutes, it's not a huge concern.
