This is like arguing that the Free Software Foundation could kill all existing rights under the GPL because it owns the copyright in the license. If Hasbro/WOTC took that position the most powerful entities in the open source software world would get involved because it would be a catastrophically disastrous precedent for them.Their position is that they are part of those agreements, because they own the OGL's copyright. Hence their purporting that they can revoke the license (though that remains iffy). In the event that they're right, they can refuse to let anyone else publish new material under the OGL v1.0a, whether it uses their SRDs or not.
