That doesn’t really have the same rigidity. There would be no guarantee for others that it would remain available to them as long as they adhere to those principles.
Said another way, a bad faith actor could create a patent and make it available to FOS developers, but then turn around and sell that patent to someone who will charge those same developers.
I suppose you could have a third legally binding document that stipulates the terms of use, but kinda wish it was just handled under the patent.
