Mike Hearn is also the guy that is proposing to build blacklisting into Tor, as well as reduce the fungibility of Bitcoin with built in taint tracking and rejection.
What is wrong with a tor node wanting to block something going through their computer and network? It is their connection you're using and are under no obligation to forward any traffic to you in the first place while they risk themselves, and you're still free to use a different node.
Keep in mind that's only possible due to a flaw in Tor. The Tor devs are fixing that flaw, and mike posted on their mailing list telling them not to fix it, because he wanted it used for blacklisting. If you don't like Tor's anti-censorship ethics, I suggest you don't contribute to it at all. Equally if you do, then your "property rights" include the right to choosing to use a system where no-one has the ability to censor.
