So a pretty transparent way to tie IMEI to someone's identity and track their location under the guise of "finding lost phones" and "checking your phone's authenticity"
That's already the case for most places around the world, unfortunately. Though, this does make the link rather obvious, which is a bit more surprising. Normally shady tracking just happens through a combination of data brokers and leaked databases.
IMEI is already tied to your identity. You need ID to buy a phone or a SIM.
