The hard part imo was not being exposed to, or unknowingly redistributing illegal content. They claim this new freenet solves this but the details on how weren't super clear.
Now, whether giving up anonymity was worth it is a separate issue.
Citation needed? IIRC, the general advice for running a Tor relay is "don't, unless you want an endless supply of abuse complaints". So you'd require a jurisdiction that ignores abuse complaints.
