While I don't think this is well done and others have already pointed out various sources from which it was plagiarized, let's apply your assertion to other disciplines:
Stealing jokes makes comedians angry. Stealing good jokes makes comedians even angrier. It doesn't justify stealing. Using steroids makes athletes angry. Using steroids to win makes athletes even angrier. It doesn't justify using steroids. Taking credit for someone's idea makes inventors angry. Taking credit for someone's successful idea makes inventors even angrier. It doesn't justify taking credit. The same goes for artists. Engaging in lazy shortcuts, theft, fraud, and dishonesty becomes more unethical and aggravating the more successfully it's exploited.
