It's not a problem to acknowledge any body part or attraction to it. It's weird to signal that ads not prioritizing showing off the boobies means they're missing something (referring to the desexualizing comment).

The actress has nice large breasts. Great, I like them too. AT&T didn't rely on them to sell products, but instead decided to focus the viewer's attention on their products and services. What's wrong with that? It's a mobile internet service, not Hooters.
