> [...] provides more protection for the contributor (Facebook) against software patent claims of licensees. It’s odd that a community so opposed to software patents would find this objectionable [...]

While confusion about the license might be behind some or most of the community reaction, the fact that the license refers to litigation over any patent, not just software patents, neutralizes this punchline. Correct me if I'm wrong, but this clause positions Facebook to fight any patent infringement suit with a software patent infringement suit, which is not in the spirit of the opposition to software patents at all.
