Two years have passed since Jon Moxley departed from WWE, after which the former WWE champion both debuted in AEW, and publicly vented his frustrations with WWE's creative direction on Talk is Jericho.
Speaking on The Bill Simmons Podcast, Stephanie McMahon addressed the former Dean Ambrose's exit, and referred to it as a "mutual decision"
“In his particular case, he was leaving anyway, and I do believe that was a mutual decision. Though, I wasn’t a part of those conversations," McMahon said. "His case is a little bit different, but I remember back when it was WCW and the Monday Night Wars and our talent were getting stripped away and showing up on their show. I think it taught us a lot about business. Handshake deals don’t necessarily matter at the end of the day. You need to have contracts. You need to do business differently.”
Moxley's last match with WWE took place on Sunday, April 21, 2019, teaming with Roman Reigns and Seth Rollins to defeat Drew McIntyre, Baron Corbin, and Bobby Lashley at a WWE Network special entitled "The Shield's Final Chapter."
