During a Twitch stream, AEW star Matt Hardy discussed how WWE runs as "strictly business" and the company's talks with NJPW:

Hardy on WWE’s talks with NJPW: 

“They (WWE) were willing to actually work with New Japan for a little bit for Bryan Danielson when they were trying to re-sign him. That was one of his conditions, he wanted to be able to go to work with New Japan and whatnot. You know the whole scenario. I don’t know. They’re open to doing it. The thing is with those guys, I think it’s pretty much their way or no way. So sometimes it’s tricky working with WWE.”
