> many open source licenses have exactly such terms in order to fight software patents This misses the point. If you want an atypically wide patent grant (covering not just patents infringed by your contributed code, but also to future contributions by other people which infringe a patent of yours), then that should be done openly and explicitly. Not by the backdoor with a clause that doesn't appear to do that but could be interpreted as doing do if you took it to its logical conclusion. (Though it's pretty clear that doing do wasn't actually their intention, given their FAQ denies that interpretation - see DannyBee's post)
