Lol. Do you really think only govts can track you via your phone ? Both the phone OS providers and the telcos can readily do so, and additionally many apps ask for access that allows them to do so if you’re not careful. Refer the jogging app that compromised military security in Afghanistan & the middle east for example.

That doesn’t make the flock cameras irrelevant though. It takes an additional step because a) you can’t opt out of number plate tracking and b) it’s facial recognition as well as anpr into a central tracking database.
