The problem the article points out is that it is not 'what if they sue us on a patent claim regarding this piece of software' that is the problem. The problem is that if you would bring _any_ patent claim against Facebook or any of its affiliates, the license terminates at that moment. This is obviously not a problem for everyone, but a problem no less. Using software licenses to gain additional - and completely unrelated - rights is really not something I would like to see become a trend. It sounds like going back to the dark ages, feudalism and all. Give the bullies free reign, and they will take your money and beat you up. In this case you would also have to take off your underpants and sew yourself a new pair before you can even try to fight back.
