The #srd is such a small amount of content that putting it under #creativecommons has only benefits, and zero cost -- rules can't be copyrighted, and the #ogl was perpetual. Many other games already use CC. Negative association with brand doesn't make sense, as the SRD doesn't contain any brand stuff.

Another upside, is that it leapfrogs the #opendnd and #orc crowd -- so are Paizo #pathfinder, @peginc@savageworlds.social #SavageWorlds, Chaosium #basicroleplay all now going to move to Creative Commons as well? That would be great.
