Nope.The Find My Network is an ecosystem that Apple controls. They introduced it a couple of weeks early so it didn't get overshadowed by the AirTags. The AR support for AirTags is going to overshadow everything else in that space. You misplace your keys, you look at the AR FindMY app, and you see a real-time image of your room with a balloon on a string tied to your keys.
The Find My network is the product. This is what it is all about. A little plastic tag with a chip in it is not. Anyone can make that, and they do. There were even new trackers announced on the same day from third parties with support for the Find My network.
It couldn't be more clear if it were written on the roof of Apple Park.
