Yes that's exactly what's going on. He's attempting to externalize his guilt/shame to create a socially acceptable situation for criticism-- to validate his internal negativity and hate.
You suggest hate as a primary motivator. Hate is based on repressed anger, and anger is the archetypal emotive of rules that have been broken. What rules do you suggest that he feels have been broken? Perhaps some kind of rule that the things that are valuable are those that are unique and not derivative? What would you suggest is the causative agency of such a feedback based rules paradigm?
I suggest the "causative agency" is the voice that says "I am supposed to be getting all the attention. Why is he? He didn't even do anything amazing!"
