This is fantastic news. They also said they will go to court over if WoTC try to “deauthorise” OGL 1.0a which is just epic.
Edit: The site went down lmao. Epic stuff.
Edit: BTW, Paizo is the company that also recognised their Union without requiring it to go to vote or hiring anti-union shitheads.
Matt Mercer did like a tweet saying that old OGL is good. I suspect that they have their own legal stuff as WotC has published them before and DnD Beyond does sponsor them. They also have been publishing their own books and seem to have been trying to distance themselves from DnD lore. I suspect it is just some nasty behind the scenes stuff. I won't be surprised either way.
