Them calling it sports entertainment, calling the fans the WWE Universe, etc was a Vince thing, and this whole build to WrestleMania, this whole renaissance of the WWE only happened because 1) AEW is semi-viable competition for talent and 2) Triple H took over creative from Vince.
A lot of why WWE was what it was for the 15 years before Vince got forced out is because Vince would throw a fit and re-write episodes of Raw and Smackdown the day of, so shit wouldn't even make sense. The terminology thing however is entirely just a "Fuck Vince" thing.
