See, what's funny is, I don't even AGREE with Ditko's objectivist views, but I still think O'Neil did the wrong thing by changing them. If anything, having such an uncompromising protagonist can create even MORE ongoing drama, if you address and explore their beliefs, and how those beliefs fuck with their lives - indeed, McDuffie did exactly that in the JLU cartoon, by presenting the Question as a two-steps-shy-of-Rorschach conspiracy theorist.
The Question without his Objectivism is like a Spider-Man who doesn't believe that "with great power comes great responsibility" (ie. much like how Peter Parker is being written now) - he's simply not the REAL character without it.
