Is it suggested that Branson, Bezos et al have awarded themselves FAA Space Astronaut wings? If a commercial organisation wants to call people who have ridden to space (or their version of it) in one of their craft an astronaut and give them wings, who can stop them? I doubt NASA would be confused by the difference between FAA Commercial Space Astronaut and Virgin Galactic Astronaut any more than a captain of an airliner would be confused with a PPL.
