Cease & desist in your illegal attempt to deauthorize and effectively revoke the OGL 1.0a.
There is no path forward without this simple fact. You do not have this authority. Ryan Dancy, one of the architects of the OGL, has stated that if this was a power they wanted WotC to have, they would have included it in the original license. To quote him:
"Hasbro also does not have the power to change the terms of v1.0a. They cannot modify the license to insert new terms limiting your use of the content, or removing your right to use the Open Game Content they published as per the terms of the license
FOREVER"
You yourselves have acknowledged this on your own FAQ about how the OGL works, which you have shamefully tried to scrub from the internet to hide your prior stance. Those words did not go away. To quote you:
"Q: Can't Wizards of the Coast change the License in a way that I wouldn't like?
A: Yes, it could. However, the License already defines what will happen to content that has been previously distributed using an earlier version, in Section 9. As a result, even if Wizards made a change you disagreed with, you could continue to use an earlier, acceptable version at your option. In other words, there's no reason for Wizards to ever make a change that the community of people using the Open Gaming License would object to, because the community would just ignore the change anyway."
Cease & desist in your illegal attempt to deauthorize and effectively revoke the OGL 1.0a. This is a path that will only lead to litigation, possible class action against you, and possible anti-trust suits. I can't help but think there would be plenty of software companies who would want to aid any legal case against you, given that they would not like to see a precedent set that someone could just void a license because it does not align with their financial goals.
This will bring you more financial pain than you would gain from your actions.
