Oh I think many of the jokes are about him. Of course they're about him. He got rich by killing people, he did it intentionally, all of his family and friends knew exactly what he was doing, and almost nobody respects him for it.
It's kind of comical if you think how pathetically small the reward for information was. $10,000 and then now it's up to $60,000. That's how little his family wanted to track down his killer? That's how little the government cares about who killed him? Jesus.
And UHC has already removed his profile from the website and is talking about a replacement. Part of me was like “I bet one of his colleagues arranged this so that they could take his job.” The jokes are all rooted in a shared (rightful) hatred towards the US healthcare system.
