May I ask, in all ignorance, and showing that I may not understand what you're saying? If GOOG were "favoring" the content of adsense materials (or "sponsored ads" displayed with search results), by an act of including more Nexus phone ads on a web page than would be implied by context, would that be strictly ethical?
