I didn’t know this franchise, but I found the article an interesting read.
The only thing that confuses me is that now DC is able to do absolutely whatever they want with it, since it’s in the public domain. They don’t need to negotiate with him at all. He said he didn’t care though, but I fail to see how this works to preserve the spirit of his work or how this damages DCs business opportunities/revenue streams. Perhaps someone can point the obvious to me?
(Sorry OP I don’t have an answer to your question)
