If Paizo wholly owns the IP (PF1E: No, SF: Maybe, PF2E: Probably), then they can move to a competing license like CC-BY-SA. That would solve the "cannot distribute their own products" problem, but it would mean their entire ecosystem including third parties would need to propagate that change.

It also doesn't change the fact that Wizards could argue they have an OGL v1.0a+ license, and use OGL v1.1 to put pathfinder 1e srd on their new vtt without paying paizo for example

Yes, now I understand. Thanks for this and your other explanation.

If I were Paizo I would sever Pathfinder entirely from the OGL, especially if they rewrote their game from scratch, and ask modules writers to switch to the new licensing. But what do I know?
