This is my interpretation, yes. The language you are quoting is largely legal boilerplate. In practice, how it works out is that (a) if you want to do a game, there's a very good chance (though not a guarantee) the answer is simply "yes", and (b) the questions of who owns what IP are all very clear, and often in favor of the individual. For example, if you go the Apache 2 license, that actually comes with a patent grant as well. In any case, the specific claim I made is that it's more enlightened than the Amazon policy, and I don't think that can really be questioned. Just the fact that large parts of the policy is public is itself relevant here - other discussion threads are arguing whether the posted text is authentic.
