You may be right, but I can’t imagine how they’d actually pull it off. The internet as a medium just doesn’t work that way - there’s always going to be a flag or a call for me to go pull ad data from somewhere else, and someone somewhere will write code that ignores that command.
Great for them if they figure it out, but the medium doesn’t work in their favor. They want the frog to be an elephant, and when it proves to be a poor elephant they cry to the govt. to fix it with laws and dmca takedowns and whatnot. That’s just a waste of taxpayer money, and annoys people on the medium.
