Its a network effect. Its basically the dominant players become more dominant. It makes apples phone's more useful, and Apple is unlikely to let any competitors use they're phone for a similar service, especially not by default. If you have an iOS device, you're tracking all these airtags around you physically for Apple. Apple's not paying you for that service. It probably uses a little battery life, but all these individual device make the network great. But if you bought an airtag that's a great thing.
