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 to all the data.
What you are referring to is legal court ordered surveillance, which requires a warrant.
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!
