Option 3 was supposed to say: "No, I don't think MS will backtrack on Windows 10 and I think the next version may be even worse". Too late to edit, even before it got any votes (MDL forum permissions). Sorry.
It is a matter or choice, all SNS, google, apple, and many many web site can easily get you info, the different is are you willing to give them. For example my contact list and photo had sync with google, but not with facebook, just because I don't want these info stay on facebook, I have choice. But Microsoft don't give us a choice, even 99% of people may end up willing send data to microsoft. Choice make people feel safer. (actually we know it is not) Same story of windows update, people like choice, even 99% of people may choose the same options (in this case: auto update).
