That sounds like fraud to me, I wonder why the people placing advertisements with Google aren't suing over this. I guess it is pretty hard to prove though? Google ads are supposed to be helping create new purchases, not helping predict purchases that would have happened anyway.

Who told you that?

It's really hard to convince someone to buy something new.

It's much easier to convince someone who is already planning a purchase to choose your shop rather than someone's else shop.

Of course Google ads were targeted on the latter auditory rather then former one. From the day one when ads were served only near search results.

Predicting purchases is a different to redirecting purchases from one vendor to another vendor.

What would they sue over? You order ads to be shown to interested people, they show ads to interested people. And then you work out how you are going to pay for those ads: per click, per view, per click-conversion, or per view-conversion.

And if you pay per view-conversion, obviously the algorithm will optimize for that, resulting in this effect.
Even if ad networks wanted to, I doubt the AI could be trained to "maximize conversion rate, but by creating new purchases, not predicting them". (They would if they could, because customers will notice a 30% conversion rate with ad broker A resulting in higher sales than 30% with broker B.)
