Correct this protection is not offered to advertisers. Advertisers have no legal rights to leverage to get access to such a feature.

However, it is offered to Brands that own legally protected Intellectual Property. Through Brand registry Brands can have their search pages protected when the customer searches for legally protected keywords (eg AirPods).

Context: I was the lead engineer that worked with the Ads teams and designed the architecture to integrate Brand Registry and Ads systems.

Even when I worked there (ie while the feature was still in Beta), Apple was not the only Brand to get this treatment. There were many other Brands in the beta for this feature.
