Google can (and has) changed large things about their platform that may negatively impact their users (~90% of the internet population which is ~3 billion people -- larger than the population of any single country) and their users don't really have much of a choice.
For instance, changes to PageRank have negatively impacted websites and business consistently in the past (so much that there's an industry around making pages cater to the whims of an unauditable algorithm -- SEO). I think the fact that websites obviously cannot just switch to a competitor (unless they want to stop catering to a potential market of 3 billion people) rules that as being monopolistic behaviour.
That's what I mean when I refer to a monopoly. If you have exclusive control over an algorithm that affects more people than any government body on earth, then you are a monopoly. Same argument goes for quite a few of their other products (if your personal mail server isn't effectively "blessed" by GMail you cannot communicate with the majority of internet users), but Search is the most obvious one.
