The first assumption the author makes, that "1. Everything Google does is open (either because Gruber believes this a priori, or because Google says so or someone somewhere believes this or something)" is missing the point. The point, to me, is that Google is not entirely open and no one should expect them to be as they are a for profit company. The problem is that Google tries to create the perception in the public eye that they are open and create products that are open and free when the reality is that they are an advertising company, not a non-profit aid society.
