I've looked in to the question and I've changed it so that even the MobileAds SDK is only initialized if premium is not active when the application is first created. This way, if premium is enabled, AdMob is not touched in any way at any stage of the application's lifecycle. I asked whether or not this initialize call I was worried about actually does anything with respect to tracking and the only answer I've gotten so far is a "no", but I still need to do a little more research to make sure there aren't any other possible ways you may be tracked if ads aren't ever being loaded or requested. This additional check will go live in a day or two and I'll update you if I find any other potential issues.
