Questions for the contract lawyers here.
Does the situation around OGL 1.1 fit the definition of coercion for designers and publishers?
Does the situation around OGL 1.1 fit the definition of undue Influence for designers and publishers?
Does the situation around OGL 1.1 fit the definition of unconscionability in the terms given to designers and publishers?
Does OGL 1.1 fit the definition of misrepresentation as it claims to be an open license, but does not fit the generally accepted definition, not being copyleft?
If yes to any of the above, does that undermine the ability of WotC to enforce OGL 1.1?
1. No, very probably not. Moreover, questions like this are wrong-headed in terms of the legal remedy which flows from it. Are you trying to escape a contract, or claim reliance damages? If not, this has no application. Going beyond that,
coercion amounting to the tort of intimidation is to employ unlawful means towards a goal, to deny or discourage the other party of a right to do something he was otherwise lawfully entitled to do. A new contract, even if it contains some legally uncertain terms within it, is not
clearly intimidation. You are off course and adrift at sea here. This isn't a helpful line of questioning.
2.
Undue influence is an area of the law which arises in Estate litigation (re validity of a will), or less often, under a power of attorney for an
inter vivos gift. It has no application here.
3.
Unconscionability is an aspect of contract law which after
Uber v. Heller now varies widely, even among common law jurisdictions. Again, its purpose is to avoid a contract or a part thereof - so the court can "blue pencil" and strike out a plainly unconscionable term(s), while keeping the rest of the contract as enforceable. I don't see how that has any application to the issues discussed here - at least
so far. It might arise later though. Leave that one with a pink post-it note stuck to it and shuffle it off to the side for the time being. Unlike the first two questions above (which have no application here) this one
might, depending on the context and circumstances.
