Even with WotC moving the 5e SRDs to a CC-BY 4.0 license, I don't think that undoes the harm done by WotC. Any time a hobbyist or independent designer who wants to do their own remix on F20 games but doesn't because they are afraid of screwing up the licensing between multiple, maybe incompatible licenses, it's a loss to the scene.
On a personal level, I won't call it a win on the licensing front until WotC releases a D&D4e SRD under the OGL and/or CC-BY 4.0 license. I'm one of the sickos who prefer 4e over other editions, and even today there isn't a game that does it quite like 4e did. I'd love to see more overtly 4e-derived games out there.
