When it comes to Tor "If they find the hidden service, you have much bigger problems to worry about" means that you have much bigger problems to worry about, because tracing hidden services is trivial. Nobody should operate thinking that the anonymity of a hidden service is doing anything for them. Hidden services are meant to hide the location of a server, not to help the clients connecting to the hidden service, and attacks for tracing hidden services to guard nodes have been known for years now, making hidden services at best equal to using three different frequently changing single hop reverse proxies. Lack of ability to locate hidden services by the feds could only be deemed sheer incompetence honestly. The good news is that clients are much harder to trace. But they become much less much harder to trace when they are switching entry guards three times a day.
