Chrome is not faster than Firefox, that is a myth. Secondly, yes Chrome does phone back every url you visit, that is not hearsay or conspiracy, all you have to do is open wireshark or some packet dumper and see all the SSL connections back to google - when you're not even visiting google.... If you think they don't use that data, then go ahead and join the Anglo Rank team, who by the way were happy using Gmail for their sales.
So I don't know what you're talking about here, all I know is if you do black hat seo using chrome or webmaster tools you WILL be caught and you WILL be profiled forever.
