This is precisely the same kind of trickery Apple 
  pulled with its HTML5 Showcase for Safari, which 
  locked out other more compliant browsers in order 
  to make Safari shine line a beacon of hope for open 
  web standards. But Google isn’t building these 
  experiences to make the web look good: it’s building 
  them to make Chrome look good.

I don't get this bit. Isn't Google doing the same as Apple, then?
