Well, I haven't seen the GSL yet, but they've renamed it due to 'Open' being a misnomer, and it's been said that it will be cast in such a way as to make complete games such as Conan and Spycraft impossible.
I think Dancey was right about the whole 'network externality' thing. And I base that partially on my own experience.
For around 15 years, I and my gaming group didn't play D&D. We played mostly RuneQuest, but we also played Megatraveller, Torg, Ars Magica and a few other games. We quit playing D&D in the mid 80s because we wanted things like skills that just weren't available in D&D prior to 3rd edition.
Because of this, I had basically no exposure to D&D rules. I didn't know what was going on in the world of D&D, and I didn't care, because I wasn't invested in the system. When I looked at 3E, it was originally because I had heard that there was a game that was putting Open Source principles to work (I am a software engineer) rather than hearing about how great its rules were.
But I'm pretty sure that , had I been playing a game based on d20 during all those years, D&D would have always been in my mind, because of the inevitable cross-polination between the games I was playing and D&D.
When I convinced my gaming group to try D&D, it took a really significant effort, because everyone had significant rules mastery in competing systems and didn't really want to switch. If RuneQuest hadn't been essentially a dead game I am not sure we ever would have -- the main argument that won my friends over was that it would be way easier to get players.
Had we already been playing a d20 game, the barrier of entry for playing D&D would have been way, way less.

This bit is interesting:
OGL only partially delivered on this, at least in terms of D&D. We got 3.5, but a lot of people fussed about that. I suppose the best evidence of the above part in action is Trued20 (developed externally) and Star Wars Saga edition (developed internally).
Also, I suppose the splat books positively incremented the design. Swift actions, skill tricks, maneuvers, the Warlock's implementation of arcane magic (non-vancian).
In any event, we already know 4E is going to have annual core book releases. And one of the purposes of Gleemax is to foster a place to discuss and improve the game. So it sounds like 4e is very much sticking with at least the quoted part of the OGL's goals.
Why do you say WotC is moving away from the OGL?
