If this was coming from an open source community (instead of Google) that's developing something like Android to give away for free, I would have understood. But, Google gives away Android for free so that it can sell loads of them and there by locking down most of the users (non-geeks) to the Google Ad universe and earn its revenue by selling loads and loads of Ads. Its not like Google genuinely cares about the expensive mobile industry and its actual intent is to provide cheap phones to those who can't afford it (on the lines of OLPC). While whether or not patents and specifically Software patents is good or bad for the society is a different argument, this issue doesn't deserve the same sympathy that companies who are attacked by patent trolls do.
