"However, it seems that Google doesn't care much for having a free and open video format. Most of the bits you put out on the web are in patent-encumbered formats, and this doesn't seem to bother you. Rather, you promote patent-encumbered formats in your new experimental service [4]. The web is based on free and open formats. Google would not have existed without the web. It will be a terrible tragedy if you tip the scales in favor of patent-encumbered formats on the web. We expect higher standards from you."
