DC hasn't paid the Siegel and Shuster heirs bupkis? Haven't they settled like 3 different times? How many more times is it going to come up?
See, people want to say it's all agenda-driven but at least half of it is that they don't want to pay royalties for legacy characters so they just want to create replacements. But they want all the fandom to seamlessly keep following the new version as if there's no difference.
Maybe if the legacy payments become too great, Warner will let Supermam finally slip into the public domain.
They just need to do the right thing here!
