In the article there's a screenshot that strongly implies the ads will be coming via email ("this consent supersedes any prior email unsubscribe notification I may have with AT&T")
So are you saying that you lack the ability to discern AT&T's GigaPower ads from other ads, or are you saying that AT&T's ads are indiscernible from other ads?
I have also been unable to discern ATT's gigapower ads from other ads.
