Have you got millions upon millions of dollars to defend that position in a lawsuit file by WotC/Hasbro?
I absolutely agree this is the biggest problem - the
actual legal position is purely academic if nobody can actually afford to fight it in court. I'd imagine a class action suit by a large number of 3PPs
might work, possibly backed by crowdfunding, but I don't know how likely that would be.
That said, we still don't know WotC's real intent here. As others have mentioned, this may simply be a communications error in that they intend
only users of the OGL 1.1 to have their 1.0 rights revoked by it (which would fit with the majority of legal interpretations over what they can and cannot do) , and that everything else is speculation by people running scared. Although I can't blame anyone for running scared, seeing as many of us have our very livelihoods at stake over this.
The real question is still what do they
intend, which we can't answer until they make an official statement. I would
assume simply by prior actions (the GSL) and that they didn't revoke 1.0 on the multiple occasions that it would have made sense to do so, that it's just that by accepting the 1.1 OGL you agree to waive your 1.0 rights, and that they don't actually have any intention of suing people into oblivion to stop them using 1.0.
I would also think it best that anyone with OGL ties makes plans for me being wrong on this
