I can't believe that anyone really thinks that.
You best believe it, because it's the truth. It isn't nearly as dark as you're making it out to be.
The butter is on the bread:
John hasn't left Disney. He is on Disney's payroll as of today. You can't come back to something you haven't left.
From a public perspective, John is still in his role at Pixar, Walt Disney Animation, and Imagineering.
John is taking a self chosen sabbatical (which will end up being "life changing").
The next steps:
John will make the decision himself to retire.
John will hand keys of Pixar to the next generation of leaders who will continue to push great work and continue to make Disney's workplace a better place.
Disney has control over this story and they know what they're doing, as do some of us.
The worst that he or Disney has admitted to is "unwanted hugs". From a corporate stand point, Teddy Bear John is a loved man who contributed to some of Disney's biggest successes. He's still very much a public figure at Disney without technically being there and it's all positive.
Until he retires, maybe even after, he'll still be happily greeting guests at the Imagination pavilion. He'll also be getting his executive producer credit at the end of Incredibles 2 this summer. He's still very much there, from a public standpoint. It's all about the illusion of having control.
