The certainty is that WotC (Wot€?) wanted to stop selling PDFs. They knew this would be unpopular so they got themselves some alibi, because that's what the lawsuits are: Alibi for stopping PDF sales
I have said for years, and you can all laugh and point if you want, that "forever irrevocable" on the OGL depends solely on how bad WotC does or does not want it to be.
I think that if WotC became just an impressum of Hasbro (I mean, entirely, as in there are no "WotC staff" left, the logo is just something they paste on boxes) and Hasbro wanted the OGL revoked, they would put their shoulder to the wheel and make it happen. It would cost them a lot of bad press, it would be hard for them to do, but they'd give it a go, I'd wager.
I doubt it. Sure, a hotshot lawyer can do a lot of stuff, but IMO "In consideration for agreeing to use this License, the Contributors grant You a perpetual, worldwide, royalty-free, non-exclusive license with the exact terms of this License to Use, the Open Game Content." is fairly ironclad.I think that if WotC became just an impressum of Hasbro (I mean, entirely, as in there are no "WotC staff" left, the logo is just something they paste on boxes) and Hasbro wanted the OGL revoked, they would put their shoulder to the wheel and make it happen.
