Mike Shae (SlyFlourish) has some thoughts too:
Don't attempt to "deauthorize" the OGL 1.0a. The best way to begin to repair the D&D brand is to not attempt to "deauthorize" the OGL 1.0a. It's not even clear it's legal to do so
Release lists of the names of species, spells, magic items, and monsters in the 5.1 SRD under a Creative Commons CC BY 4.0 license. Include the lists of names of species, monsters, magic items, and spells. This is very likely material we could use anyway under copyright law but it helps if we know that WOTC agreed.
Use independent third party arbitration for hateful content. There's no way WOTC should have the sole right to decide what is hateful content.
Add "Royalty Free". The current draft OGL 1.2 does not describe itself as a "royalty free" license
Make it Truly Irrevocable. As written, the OGL 1.2 redefines irrevocable to mean that the license can't be revoked when applied to a product but not that the license itself can't be revoked. This license, on its own and applied to their system resource documents, should be irrevocable. This is the whole reason we're in this problem to begin with.
Rewrite the termination clause. As written, the termination clause in the OGL 1.2 is far too wide. Who determines if a licensee has infringed on WOTC's intellectual property? How is that arbitrated?
Rewrite the severability clause. As written, the severability clause in 9(d) almost certainly gives WOTC the ability to invalidate the license. Given that WOTC intends to attempt to deauthorize the OGL 1.0a on a technicality, I have no faith WOTC won't try it again here.
Section 3(a) - Strike language prohibiting creators from seeking injunctive relief.
Section 6(e) - Strike or rewrite to account for international laws. A creator in the US can't be expected to abide by laws in other countries and vice versa.
Section 7(b)(ii) - Expand time to cure to 180 days and better define what actions are sufficient to cure a breach.
