RE: "Am I missing something here? A company promoting it's own product before it's competitors?"
That would be abusing their position as a monopoly, the same thing that Microsoft got slapped over when it came to web browsers. I'd imagine that Google get accused of this whenever they add a new service, as they really are the leading search provider (China and Russia notwithstanding) and so in a prime position to drive out the competition from whichever market they choose to stick their nose into.
