Aren't operators of Tor relays also "aiding distribution" by that standard? They may not be storing anything (yet [1]), but they're still passing along unknown traffic. In fact they're even LESS aware of what their relays are being used for than a Freenet node operator, who can, if they choose to, both discover some of what is in their data store, and purge specific data from it given a known key (though it would be an endless battle and perhaps expose them to even more legal risk). [1] It's not hard to imagine a future Tor version implementing a successor to hidden services that involves caching or securely storing data in some manner that completely prevents the relay operator from knowing what is there.
