As the lead for some stuff at Chrome, what's your stance on Google [ab]using its strong market position to promote Chrome basically through all possible channels and muscling out Firefox down to sub-10% market share? "Upgrade to Chrome" on Google's main page irrespective of what the user's current browser is, etc. Are you happy with the resulting browser landscape?
