The problem is the subjunctive here.

It's not where the _would_ rank ... it's where they currently _do_ rank.

In my test, the AI Overview produced accurate information ("Google does not offer phone support for account recovery") but none of the other hits on the first page say anything like "Phone support calls are always fraud. Google will not call you."

I think the point they are making is that google will let the fraudsters pay to place higher than the warnings because it's profitable to do so.

If there is only one time they would honor their fair market obligations and not raise their own rankings, it would be on a cost center like free tech support to consumers.
