It seems to me that a lot of ppl here are getting thier undergarments in a bunch over a contractual issue between party A and party B, that does not involve intertubes C.
Wotc and paizo and the others are companies, which have obligations to these creatures called share holders. Share holders expect profit, and the protection of their investments, such as IP, as well they should. How do they do this? They hire nefarious arcane alienists called lawyers, that bend the rules of space, time and business to protect their employer's interests. They often have the final say in things, usually overriding the common sense of the rest of the company, bc other companies have thier own lawyers in the underdark.
If your investors and the illithid lawyers don't like that you gave away the kitchen sink with 3.5, and tell you to change things in 4e, all you can do is try to persuade them to change thier minds. if they don't, guess what, you are to implement a GSL instead of an OGL wether you like it or not.
Now that you are told to implement a GSL, you have to make sure your illithid lawyers are happy with those writing for you. Writers have thier own lawyers, and all these lawyers duel it out and jockey for control with their arcane writings until there is a scroll of binding both parties are satified with.
Would WOTC want to make sure they have good writers? I'm sure.
Do they also have to protect thier IP lest they be tentacle grappled by lawyers under the command of shareholders? naturally.
Could circumstances change once the GSL is released and they satisfy the conditions of allowing those that bought in early to have first crack? Surely, just throw a few more lawyers together in an undulating pit of horrors to get a scroll of binding.
The only negative thing that *I* see here is Nick's name being thrown about over a potential contractual/licensing dispute by individuals on all sides for their various views of which company is naughty, thereby attaching a negative stigma to Nick for future potential lawyer battles with other companies.
As an aside, i love 4E AND Pathfinder, and as long as either product continues to meet my personal expectations, that company will get what the shareholders want most, my money.
