Dumbest decision I've seen Paizo make since the last one.
In retrospect if that was their goal, it would have made sense to use a different copyleft license for the open content that did not include a clause that paints Wizards as the body to update the license, especially given the mechanics of using PF 1E content in 2E requires subjective decision making compared to the relatively automatic 3.5 -> PF1E or PF1E -> SF compatibility.
1. simplify things for 3rd party publishers. rather than worry about multiple licenses, just publish under the same one as pathfinder 1e, 3.5e, and 5e, that they already know like the back of their hand
2. save costs. writing a new license is expensive. it apparently would have delayed release of the pf2e system and significantly increased the cost
3. cover their ass just in case WotC thinks pf2e is still too similar to d&d
there’s really no way they could have foreseen a rugpull like this. everyone thought the OGL was ironclad until yesterday. hindsight is 20/20 though.
What Paizo would or could do now is a different matter. They might say that PF 2E is distinct enough, especially if some 2.5E thing would remove some remaining verbiage or direct lifts from old OGL material. They might also just do a deal with WotC. Gates and Jobs at Tanagra.
