Let's address the FUD

So while Google won the browser wars, they haven’t won the Web.

~Chrome won by Andreas Gal

Google built it to maximize revenue from your searches and deliver display ads on millions of websites. To monetize every… single… click.

~Browse against the machine by Eric Petitt

How does the web win?

  • The web is built on standards. (IETF, W3C)
  • Multiple implementations are required
  • Build for the web, not for one browser
  • Users need a browser that works for them

Overheard at conferences
