Marvel Comics and DC Comics are experiencing a "grotesque Hollywoodisation", the Stumptown writer has said.
"There was at least a period where I felt that the way they wanted to make money was by telling the best story they could; now the quality of the work matters less than that the book comes out," he told CLiNT in an interview transcribed by Bleeding Cool. "There is far less a desire to see good work be done.
"Despite what the publishers say, their interest in the talent is minimal now, the interest is only in promoting the financial worth of their properties," he continued. "That was not the case as of two or three years ago, when there was an 'Exclusives war', but that's all gone by the wayside now.
"Ultimately, they are saying, 'We don't need you', because they can get a million more just like you."
Rucka announced the end of his longstanding relationship with DC in 2010.
"I gave seven very good years to DC and they took gross advantage of me," he said. "That's partially my fault, but not entirely. At this point, I see no reason why I should have to put up with that, I can sink or swim on my own."
The writer revealed that he will end his work on Marvel's Punisher with the five-issue War Zone miniseries that will follow from issue #16.
"That's it," he said. "The powers that be at Marvel, without talking to me, decreed that he's going to join a team on another book.
"That's their choice, they own him, but I don't have to be happy about it. I am glad I had the opportunity to work on the character and I'm proud of the work I've done."
