#2 Reward for Loyalty
WWE loves and demands loyalty from its employees. There is a reason why WWE removed Chris Jericho from SmackDown Live's opening promo. Even though we bash WWE for many things, the largest professional wrestling company in the world often rewards loyal employees - sometimes with a big push on the screen, and other times by providing them important roles behind the screen.
Kofi Kingston has been a loyal WWE employee for over a decade. Kingston has endured some bad booking and rough patches over the course of these years. Thus it is only fair that WWE pushed Kingston. Kingston could have easily quit WWE and move on to the Indie scene, or other promotions like New Japan Pro Wrestling, where talents like him have brilliant scope for success. But Kofi chose to stay, and WWE is probably rewarding him now for his loyalty.
