How personally identifiable is your ear though? It’s not connected to your thoughts, you can’t use it to determine your age height and weight, which ad company would need that data? IMO, it’s no different than sending a mold of your ear tube to a CIEM company to get your custom molded earphones.
Northrup Grumman probably already have a prototype to identify you by your ears from a mile up and kill you with a single bullet the moment you’re not inside.
