Again, you can think Ron shouldn't have brought the claim, that is a separate question. The 'forum' nonsense is pure smear, though. IN THIS SITUATION WIPO is only 'empowered' by a private contract. Had they not been listed as a dispute resolution forum under the contract, Ron's claim would not be filed there.
And free market says you only get the rights your contract gave to begin with, and have to live within it.
I have my own dislike of how this went, but on the 'free market' side it seems the guy over played his hand. He only had 'rights' to what the contract allowed, and Ron's trying to buy it was out of good will, not 'right'. And it seems Ron thinks his good will was abused.
