Ok I do not know where you got that original interpretation but this is a huge part of the problem of online news PLUS fan reactions to it. Stuff is taken completely out of context or just wrong. Fans rush to share before confirmation. I appreciate that you quickly corrected what he really said. But often people will see original post and never see correction and will always believe it.
For the record I am a Arrowverse fan more than a James Gunn fan. But very excited about the possibilities for what he is doing. I think Arrowverse fans would agree with what he really said. Which was not even specifically about the Arrowverse itself but DC tv of past. That rights were handed out very casually. It's amazing a lot of it was good. Part of what he was talking about were Probably oddball things developed and never made. Which tied up rights for years.
