The irony of google policy!

We all would have read or come across the book called "The GOOGLE story". It states a very important policy also unique of that of Google which it is proud about (actually it boasts). The policy is that Google has and never will publicize itself by placing ads on other sites or asking or requesting other users to use itself or its products. Nowadays I see a lot of ads on other sites recommending about Google chrome stating it is fastest browser ever ( which actually isn't true!).

So is this is irony of the Google policy??? :P
