Are you saying that the authors of libraries used should be counted in the credits, or are you saying that Google is going above and beyond the call of duty? If the latter, I applaud you.
But if you believe Google is obliged to credit those groups in any way beyond the letter of their licenses (e.g. share credit during advertising, as we're discussing), you've got it wrong. Do you also believe that Intel and AMD, Dell and Apple, all of the implementers of browsers that came before Chrome, and everyone down to Djikstra should be credited? Because, you know, they contributed in some way to Chrome's existence too. But that is not how crediting in software or any other discipline works.
