> non-sociopathic developers have no right to complain
The very same developers that advocate pirating from Netflix or Disney?
He's pointing out the hypocrisy in a class of people (generally, tech-savvy programmers) that have no problem advocating for piracy and gleefully thwarting the concrete IP rights of businesses on one hand, while defending and bemoaning the abstract IP rights of other content creators on the other hand.
My take away is that he's saying IP rights is a weak argument to use to defend a personal position for not adopting LLM's in your workflow, especially given the context of modern piracy.
