Funny you say that, we were just talking about it:

"iOS sends the MAC addresses of nearby devices, e.g. other handsets and the home gateway, to Apple together with their GPS location. Users have no opt out from this and currently there are few, if any, realistic options for preventing this data sharing."
If you think Apple is somehow not abusing their position of power, that's just foolish. Apple is definitely one of the more evil (if not the most) companies out there.
Now they are getting into cars, tracking your Speed, your Location, How you Drive your car. And you are worried about your Windows sending telemetry about what you click on the start menu lol? Really that's your concern?
