I agree that Google wants to make the web as fast as possible and as good as possible because it's directly in their interest so they have incentive to do it. They are mostly a web company after all. On the other hand Apple and Microsoft don't really have to want to make the Internet as fast or good as possible. They either do it to support a different agenda, like not needing Flash, or from a defensive point of view, like Microsoft with IE9. But when it comes to choose between what they really care about, they won't choose the web. That's why Apple hasn't made the embedded browser as good as the main one, and Microsoft would rather use more proprietary stuff to couple with their browser, like DirectX. My point is it feels natural to these companies to use the web only to help their main objective indirectly, which is different than simply wanting to make the web better, while in Google's case, it feels natural to them to want to improve the web because that interests them directly. So when it comes to who really wants to improve the whole web the most, I'd trust Google.
