Great. If you're that paranoid, only turn your phone on to buy the tickets and when you're at the stadium. And don't use it for anything else.

This dude has previously paid hundreds of dollars per year because he wanted custom-printed tickets. He can pay a hundred for a cheapo Android to use exclusively for tickets and not give up any privacy at all, if he's more paranoid about tracking than the other 99+% of the population who uses smartphones just fine.
