amp-ads moves those ads/trackers in iframes, but that doesn't reduce the code size, right? google is also injecting code in your site , so you can't be sure that it's secure / private, right?

And if i promise to make all ads async and iframe, will google promise to rank my site higher? If not , they are discriminating in favor of their own walled garden system without an objective ruse.
