Why is the Moon now considered a planet based on Alan Stern's findings?

What exactly does his new definition change that would count the Moon as a planet? And is it possible that in the near future this new definition become the more recognized definition?

The new definition is simply that the body 1) never underwent fusion on its own and 2) has sufficient gravity to maintain a spheroid shape.

Under the new definition, moons like Luna and Titan, dwarf planets like Pluto and Eris, as well as rogue planets and exoplanets, will all be called Planets.

Basically, he hates the fact that Pluto isn't a planet and wants to redefine the term to one that allows Pluto to be called a planet again.
