They stuck with the OGL model for about eight years and that was without having the mags under their own wing and no DDI. After less than 2 years they were turning toward Essentials and then announcing 5E in less than 3 1/2 years from 4E's release while having the mags under their own wing and having the benefit of DDI, yet PF routinely outsells them now and companies like GR and others producing highly successful OGL-modeled RPGs. That's how WotC looks at the market. I look at the market share the same way WotC looks at it, but I tend to discuss it somewhat differently.
See though (and this is funny considering I was bagging on their business sense for most of the thread) they know how much money is in their bank account.
And if the OGL had actually been helpful for those 8 years they would have done it for 4e too.
So either it wasnt helpful, it actually hurt, or its affect was so negligibly small one way or the other that they couldnt be sure what the effect actually was.
Pathfinders success is if anything indicative of the FAILURE of the OGL. It literally created a huge competitor who picked their pockets for millions of dollars in potential sales.
It was awesome for gamers, and game store owners, and 3rd party publishers. But in what way did it actually help WoTC?
And was that help equal to the harm of losing all the sales dollars went to other companies instead?
I think the answer is No. And they clearly thought so too with 4e.
No, i think pathfinder outselling them is a case of the 4e rules not being fun for a lot customers, not a case of them losing out for abandoning the OGL.
