Apple could eliminate most ad fraud that pretends to be its platforms, by generating tokens from its secure enclave for advertisers, and providing a REST API to validate the token is from a live device.

And of course, as you are in this industry, you know that Apple devices are the highest quality, valuable, converting clicks in the ecosystem.

Then again, PAT would diminish inventory, prices would rise, and people would get better, but nonetheless similar, ROI that they get today.

It is intellectually dishonest to make predictions about ROI. Nobody really knows. Bot farms, fraud, those are all red herrings. Most advertising has shitty creatives.
