JBL decision to announce that he will be leaving his weekly duties on SmackDown commentary to dedicate more time to at-risk youth and communities in Bermuda was reportedly a decision he made nearly a year ago. 

JBL's leaving has nothing to do with the bullying accusations with Mauro Ranallo, in fact, Vince McMahon was against punishing JBL and certainly wasn't in the mindset of firing him. WWE allowed the situation to calm down and have since worked things out with Ranallo who now commentates on NXT.

Justin Barrasso of Sports Illustrated has also reported JBL decided in October of last year that he wanted to leave the company, handing in his notice. In recent months the former WWE Champion turned announcer has found it difficult to commit to the WWE traveling schedule. In the last couple of months, he has been arriving just in time to start his duties on SmackDown. He is simply burned out and it was his decision to exit the company. 

JBL will still reportedly be involved in Tribute To The Troops, WrestleMania, and other major WWE events.
