In that last sentence, do you mean "no longer updating the SRD frequently"?When WotC made changes to the d20 System Trademark License, the so-called morals clause, it gave them a mechanism to revoke anyone's use of the d20 System Trademark License (though not the OGL) based on WotC's unilateral decision. They only did this once to my knowledge. But they also were no longer updating the OGL frequently
Well, Paizo couldn't publish Pathfinder but for the OGL (or, at least, it would have to defend some pretty expensive IP law suits before it could be certain one way or the other). The OGL is, for Paizo, a necessary condition of their existence as a largescale RPG publisher. I mean, it's not as if Pathfinder is successful because it's an OGL game! It's successful because it's D&D (and as this poster clearly indicates, Paizo is not exactly shy about this).you claim the OGL is responsible for PF to make millions, money you claim WotC would have made in its absence, while simultaneously arguing that the OGL had nothing to do with the millions WotC made while utilizing it.

Whereas WotC, unlike Paizo, has the right to publish D&D (whichever edition) independently of the OGL (being the owner of all IP rights in respect of D&D).
So of course the financial viability and flourishing of each company is differently related to the OGL!
