H.264 was something like >90% of all video a few years ago and wasn't it free for streaming if the end user wasn't paying? IIRC someone also paid the fees for an open source version. There were pretty good licensing terms available and all the big players have used it extensively.
Anyway, my point was only that expecting Google to develop every piece of tech in the world and give it all away for free isn't a general model for tech development, whereas IP rights and patent pools are. The free ride ends the moment Google decide they need more profit, feel threatened in some way or get broken up by the government.
