Jake Platt, owner of three CrossFit gyms eating Mangalitsa lardo.
In a recent podcast (from 10:53 on), Robb Wolf, author of The Paleo Solution, addresses the issue of whether or not people should eat bacon.
From what I've seen, a very small number paleo dieters avoid farmed animals and salt, figuring that Stone Age humans didn't eat that way.
Many paleo dieters I know use bacon as a staple fat. When people cut out dairy and vegetable oils, you see people heavily relying on things like coconut cream or bacon or lard.
Robb sounds generally pro-bacon, which is good (because it means he can enjoy Mangalitsa products) - as so many CrossFitters do.
My own Mangalitsa-based program (cyclic low-carb with resistance training) seems to be working.
