To be fair, anybody can take the rules and do with it what they will. They can even sell it if they want. The simple fact that is missing from this discussion is that there is zero copyright protection for rules, only creative expression. If the "Classic" crowd wants to do a 1.5+ ruleset, Wyrd can't stop them. They can talk about it as an alternative ruleset, creatively avoid names and titles, etc. This will make it awkward and often difficult, but they can do it. The only decision Wyrd has is whether or not to allow the non-profit use of their actual IP (rules not being protected, as Eric asserts). That's not an easy choice, but it needs to be clear that they actually have no legal control of their game rules under U.S. copyright.
