> For example, Tesla has a monopoly on electric cars? Tesla has sold 5.5 million cars, If Tesla decided tomorrow that I can only charge at a Tesla charger I would consider that applicable for Monopoly purposes.

My point is, with 2.2 billion devices, that's large enough to be considered it's own market that can be subjected to a monopoly. > As I understand it, McDonalds has sold over 99 billion Big Macs. I think you're just being facetious now. Big Macs do not have their own market below them.
