It is not the advertisers, it's Adsense itself. As stated in the program policies, AdSense publishers are not permitted to place Google ads on pages with adult or mature content. This includes images content containing strategically covered nudity, as well as sheer or see-through clothing. A woman's exposed breast falls under nudity. That's just the rules.
