I would argue that 100% of the great adventures in 3e used the OGL (thats right all the official ones sucked), and many of the most interesting expansions were OGL.
I can see why it might not be the best business case to do it. But that era of D&D when every company on the planet and tons of freelancers were pouring cool content, was due to the OGL. And the gamer definetely benefitted from it.
I remember Alderac Entertainment made these 5 pg pamphlet adventures, I ran a whole campaign based on these simple themes with hobbled up maps, simply incredible. I also remember Paizos adventure paths, wow, Age of Worms anyone? Incredible. WOTC just hasn't made quality adventures like that for a while and if there not going to do it, and they arent going to allow others to do it, its going to effect the popularity.
