True yes, kinda. Legal, is more complicated and likely needs to be decided in court. There is a non-small chance that original OGL license is in no way terminated and people can continue to distribute copyright content under it. Through trademarks can be another issue. And being in right doesn't mean you are not sued or otherwise terrorized by an abuse of the legal system. E.g. see non-Lego brick products which are legal but frequently e.g. stuck in customs due to Lego abusing the legal system. Not even speaking about the 3D trademark nonsense which makes selling compatible figures close to impossible even through the law is very very clearly not meant to be apply that way.
