Tech incumbents whose businesses are reliant on selling ad space need to designate who is a verified human on the internet as soon as possible or their businesses go to zero once the entire web is AI bots and all the traffic is fraudulent and worthless, so they have to play as many angles as they can to achieve this.

That's not how ads work. They're done on a bidding system. If the value of each ad impression / click goes down, the bids will go down, but their total revenue would stay the same. It'd have basically zero effect.
