Just because a theorem is true doesn't mean you can't misuse it or that you don't need to do some work to map it to reality.

For example, the Banach-Tarski theorem is solid, but that doesn't mean you can start a business making golf balls by buying one and then endlessly replicating it.

Certainly. Just because you can name a theorem doesn't mean you can derive it either. The article had no actual computation or derivation of the theorem. Instead, it talked about beliefs and other things that don't really exist (in regards to the computation of a probability value).
