They can call Pyrodex anything they want.
However, real BP is made strictly of charcoal, sulfur, and potassium nitrate (saltpeter). It's been that way for centuries, regardless of what some marketing guru wants you to believe.
Pyrodex changed the traditional KNO3 oxidizer to something else, making a BP substitute that passes strict DOT shipping and handling regulations because it's harder to ignite. That's why you can buy Pyrodex at WalMart, and not Goex FFg. It's also basically the only reason why Pyrodex exists, because it can be handled and stored as a smokeless propellant, vs. a low-order explosive.
