Perhaps, but Apple didn't even ask about airtags, they just quietly broadened the "Find My network" across all Apple hardware to support this new feature. And there's nothing stopping apple from generalizing their "Find My" network to pass the same type of data that Amazon is.
find my is airtag location -> owner and sidewalk is device <-any data-> amazon/device owner.
airtags has privacy built in and anti stalking, tile and amazon sidewalk does not. Sidewalk is enough bandwidth you could easily drop a location track & voice recorder on someone and have it spy - voice can go as low as 30kbps.
