Here's a different take - there is not really a way to prove that the AI agent autonomously published that blog post. What if there was a real person who actually instructed the AI out of spite? I think it was some junior dev running Clawd/whatever bot trying to earn GitHub karma to show to employers later and that they were pissed off their contribution got called out. Possible and more than likely than just an AI conveniently deciding to push a PR and attack a maintainer randomly.
