The question is not whether Google can have a monopoly. Of course they can. Sometimes monopolies arise just because something really innovative got developed and no one else can catch up for a while, so it's perfectly legal to have a monopoly. What's not legal is to abuse your monopoly position. And the main determination of abuse is whether or not its harming consumers.
Delivering crappy results is not an abuse of power, because consumers have other options. Arranging the SERPs to suit Google's business interests would be an abuse, because consumers are assuming the SERPs are arranged in a fair, mathematical way. "Blending" the ads is probably fooling consumers into clicking what they believe are natural top results but are really ads, but Bing does it too, so that might be considered industry standard and not something Google alone can be blamed for.
