Earlier quoted context omitted.
What a ridiculous argument! So what is the point in having laws then? No doubt you believe any adtech request for personal data should be met by the subject promptly bending over and grabbing their ankles with both hands?
I am absolutely sure (even though I can't give a link as proof) that all telephony operators everywhere have to provide a backdoor for the "authorities" in order to obtain their licence. So, yes, a telecom provider will be bending over immediately, or risk losing their licence. I also suspect that in many cases, the operator won't even be informed about the tracking because the gov agencies already have direct access…
This is nothing whatsoever to do with allowing anybody who pays (such as adtech) a free reign over your private data to do what they like with!
