I'm just trying to objectively interpret a really small amount of data here, not make a justification for or against any particular policy. You're right that it's important to have informed consent about this kind of thing. That applies to Google, Facebook, or Amazon too. It does seem like it's pretty obvious here when there are so many statements about how Cortana gets to know you, your speech, your schedules, your flights, your interests, etc., and there's a delete button for everything too. Most people probably like all that, but I would like to see more robust privacy settings to easily disable tracking whenever it's desired.
