I hear a lot of comments like this that seem to imply that WotC has a single point of view. I realize it's often just an intentional simplification (and likely is in Dr. Awkward's case, for example), but that attitude is out there. I believe that attitude is wrong.
Well, it is a simplification, but the fact of the matter is that no matter what the various parties involved at WotC feel about the subject, or what they're doing about it, the official position of the company at the moment is "GSL: like it or lump it."
If there were a release (or even a messageboard comment by someone involved on the inside) saying "we understand the problems that people like Clark Peterson have with the GSL and see that they need correcting in order for this thing to work. We are working it out," then things would be different.
As it stands, WotC does have a single point of view, because it's a company, not merely a group of people. And that single point of view is currently that the GSL is what we're going to have to live with. As far as the buying public is concerned, it doesn't matter how the various WotC employees feel about the license if:
1. There is in fact no move toward fixing the situation in process, or,
2. We aren't aware of any such move.
Either way, we're left with the collective corporate voice of WotC putting a deal on the table that Clark sees some big dangerous holes in, and no hope at the moment that anything will be done about those holes. As far as we know, WotC the company is pleased, despite the gnashing of teeth on the part of some elements of that company. So that's the situation we are left to make commentary on. Without at least an official acknowledgment that there are problems with the license, we really have no reason to believe that anyone's concerns are going to effect any change, whether those concerns come from Necromancer or The Rouse.
