5. Summation
The OGL was meant to last forever. It was meant to be irrevocable and permanent. It was never meant to be "De-Authorized" at any point. The terms WotC is trying to use to get rid of it -now- did not exist as specific legal concepts when it was written, and the architects of the OGL have explained that, repeatedly. There is no situation where getting rid of the OGL 1.0a is a good thing or a positive step. Particularly since it shows WotC is entirely willing to blow up any deal it has previously made to increase the control and power they now possess for their shareholders.
WotC can no longer be trusted by third party publishers. There is no real "Path Forward" after this. The best they can do is enshrine 1.0a and pretend this fiasco never happened, but the ORC is still going to be written. And most publishers aware of this event will be signing on to it, or Creative Commons, or some other license that offers real stability long-term.
Even if they took out all the poison pills, it still can't be trusted. Wizards have shown they'll change terms whenever the like. No contract will ever be held in good faith.
