Does apologising before criticising someone's creation make you feel less guilty about doing it?
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!"
