There was a phrase I heard years ago that I really like.
"Forgiveness isn't about letting them off the hook. Forgiveness is about no longer allowing them to have the power to affect your emotions."
What's the other phrase? "You can't have redemption without repentance?" Something like that.
As a 3PP, I'm glad they backtracked. I really am. I don't think they had to if they didn't really want to (see other various posts I've made on the topic re: the importance of branding, how most gamers aren't on forums, etc.). But I'm glad they did.
But...
And that's a big but, trust is important. Before going back, I'd need 2 things: a big carrot, and protection/peace of mind they couldn't do it again. As a 3PP, I don't see myself using the OGL 2.0 going forward. Who knows what the future looks like. But with the move to CC, I can assure you that future products won't be using the OGL 1.0(a). Why? The CC offers me protection and pretty much the same thing I had before. I never used others' Open content anyway, so it doesn't impact me.
