> Why did Paizo use a license not designed by them? Let's imagine a scenario: 1. Paizo releases Pathfinder 1E. It's uses material from D&D 3.5 SRD which requires it to use the OGL. 2. A third party releases a campaign for pathfinder 1E. It uses material from pathfinder 1E which requires it to use the OGL 3. Paizo releases Pathfinder 2E. They change to CC BY-SA for their open components. 4. I now want to update that campaign to the 2E rules. But the original campaign publication insists I must use OGL, and Pathfinder 2E insists I use CC BY-SA and now I cannot. I think a mix of (a) the scenario above, (b) legal CYA in case it was found Pathfinder 2E was too close to 3.5e material and (c) using what they're used to led to the decision to continue to use OGL for Pathfinder 2E.
