Gaming is fun, and fun is for everyone
They don't need to though - companies simply don't inherit that stuff. Look at the issue of Disney not paying royalties to writers (most notably Alan Dean Foster) who have written for franchises Disney later bought. I believe they eventually accepted a moral responsibility, but legally, Disney was right - the company that owes you money does not exist.
I don't entirely disagree, but I believe it's a little less black-and-white than that. I believe Disney is suing Steve Ditko's family and others for trying to get copyrights (that I assume would be legally predating Disney's ownership) so there's some debate on whether new ownership means a blank slate of responsibilities.
