I'm aware of that. My point was that not much has actually changed in practical terms. Yes, there is a little "Ad" text and slightly different background, but both before and after, the first thing people see when they search for "google chrome" is the Chrome download page.
Here in Denmark Google doesn't advertise their browser. However Microsoft does. So a search for "browser" returns an ad for IE, wikipedia as the top result, and then Firefox, Opera and Safari without Google Chrome anywhere on the first search page. So it definitely has changed in practical terms.
