Bolded from your quote: You made that up and you know it. It's really funny how you pretend to lack knowledge when it suits your narrative. I'm pretty sure you know how targeted advertising works. You know it's a fact that Google doesn't give anyone's data to advertisers. Pretending to be dumb just to be able to post stupid stuff is beneath you. You're better than that.
What difference does that make? Someone posted something an MacRumors, and even before someone else made another post, he found an advertisement clearly matching his post. Do I care, or does anyone care, what exactly is exchanged between Google and the advertisers? What I care about is the effect: Post on MacRumors, advert appears.
