I don't think you get

Funny thing, Ryan Dancey actually had a bit of a prediction on what would happen if WotC went away from the OGL. He predicted that some other company would pick up 3e and run with it, WotC would be forced to go in a direction that would be criticized by many as "not D&D," and would hurt for it, sales-wise.
If you think WotC was hurting for sales under the 4e banner, one credible explanation for that is that they
rejected the OGL. Indeed, it's the GSL that pushed Paizo into making Pathfinder in the first place...so they wouldn't even be competing with themselves if they didn't go in a different direction.
If the OGL is so clearly a horrible business idea, why might it be that the most popular tabletop RPG on the market today is fully OGL (to a degree even 3e WotC didn't embrace)? How is that even possible, if OGL is so horrible for the bottom line?
I mean, maybe, but what you just described is essentially free market competition. You're saying that's harmful?
Just so my cards are on the table, I'm a fan of OGL. For a lot of reasons. Smart business among them. PF isn't the game for me, I'd much rather drink 4e's kool-aid, but I think what they're doing with the OGL -- while simultaneously selling like hotcakes -- at least casts doubt on the largely evidence-free anecdotal idea that the OGL is horrible for business.
Credible rumors? Or are you poking the bear with a stick here?
