Why do we really care any more?
I was all about pushing for a better GSL back in the day. But now, it seems like everyone has either:
1. Given up, and hitched their wagon to a different horse - decided to instead invest in Pathfinder, True20, etc.
2. Decided to sign on to the GSL despite its predatory nature, and hope for the best.
3. Put out 4e-compatible stuff without the GSL.
Let's say the new GSL comes out and it's much better, perhaps as reasonable as the old d2STL. Is that a compelling enough case for any of the above 3 folks (well, #1 and #3) to change their direction? It doesn't seem like it; it would have to be as revolutionary as the original OGL to cause people to change direction at this point and everyone knows that's not going to happen.
