There's a key distinction between Tor and Freenet. With Freenet, all nodes host content, access content, and relay traffic for other nodes. But with Tor, only clients (including onion services) host and access content, and they don't relay traffic. Conversely, relays merely relay traffic, and don't host or access content. Also, only entry guards ever see the IP addresses of clients. And they only see encrypted data going to middle relays. So attacks like police have used against Freenet are impossible. Because clients never connect directly to each other. The closest analog is taking over an onion site, and then serving malware to users. But that's much harder than running nodes, serving child porn, and logging IPs. Also, given that relays retain no content, operators have so far managed to escape liability.
