Yes, there are high-moral reasons to run an exit node too.
Gun dealers also know their guns can be used to shoot people. Are they culpable in every murder?
Every kind of entity can receive orders under the Wiretap Act, whether it's "regulated" or not. My friend who runs the server where I have my e-mail could receive such an order.
Until the D.C. Circuit accepted law enforcement's reinterpretation of CALEA in 2006, ISPs were not required to buy or have wiretapping equipment, but they were required to comply with wiretap orders to the best of their ability.
Tor node operators are presumably also legally required to comply with wiretap orders to the best of their ability.
Does your theory suggest that ISPs' liability would have been different before 2006 because no specific regulation treated them differently from Tor node operators with respect to wiretap obligations then?
During the Pirate Bay trial, the requirement was set to "primary usage". They took a screenshot of the top 100, and sad "obviously, the site founders know that the primary usage was illegal" which the court then accepted. Arguing that same for tor is sketchy at best, and there is government organizations, researchers and developers who would argue that the primary usage for tor is as a privacy tool for non-criminal activities. I also suspect that they would have plenty of evidence to back it up.
Yeah sure. Just install Firefox privacy extension and you are running Tor. Or your children can do it for you.
You can't have a really secure anonymous untraceable network, but also monitor everyone on it for illegal activity. The entire point of that network is illegal activity, for local definitions of illegal.
