But anytime it sends a ping, it reveals the fact that an iOS device is near. If it's a public place where lots of different people pass by, then that information doesn't identify anyone. But if you place an Airtag at a private location, eg. near someones home, you can use it to detect when the people living there get home. Now maybe you don't worry about side channels like this, but I really think that it should be up to the individual user to decide whether they want to risk something like this or not. It's quite telling that Apple does not ask people to opt-in to the Find My network, while every third party app needs explicit user permission for any kind of Bluetooth access.
