His history of designing JavaScript, co-founding and CTO-ing the Mozilla project and being a general expert in coding and the web? Yeah screw this guy. No way he'll ever be able to develop a successful browser.

If you make your technical decisions based on, as far as I can tell from Wikipedia, 1 minor political disagreement with the project lead then you'll be as limited as Stallman when it comes to using a computer. That is an extreme position.
