Varma, in particular, seems to have come down with a severe case of Silicon Valley Brain and is under the impression that he's competing with Chrome, et al. on Chrome's terms.

He needs to be thinking differently about protecting the WEB as the WEB, and thinking about what Mozilla can do to repair the Internet social contract that Google's actively torching.
