I wonder what organization owns his likeness? MGM? Sony?
All these "stars" have millions of pictures on file with their management companies that own their likeness. There's absolutely no way of knowing if this is a real person or not and it's not even illegal for them to create messages with their image stating any point they desire.
I would assume contracts at that scale are negotiable for renewal every 3 years or with some spanning much longer.
In other words, we will continue to see these asshole say ridiculous bullshit for years to come.
