That line also struck me as odd. I feel like these guys maybe don't understand their customer base.

I have no need for this service, and would never register a business address to it for all the legal reasons being discussed in another thread on this topic, but I would have registered a private domain or two there anyway, just for the sake of supporting something I believe in.

But that sentence sunk it for me. If you're gonna offer an anonymous service to help promote freedom of speech, it can't be just the kind of speech you like. It's reasonable to say "nothing so illegal that we're gonna end up talking to three letter agencies about it", but beyond that you're either promoting freedom of expression or not, it's very much a binary thing.
