Is Disney no longer owned by Winnie the Pooh?

Excuse me, but could you clarify something for me? I've come across a rather unusual claim, stating that Disney is no longer owned by Winnie the Pooh. As a matter of fact, I'm quite certain that Winnie the Pooh is a beloved character from the Disney universe, but I'm absolutely puzzled by the suggestion that he might have been the owner of the entire company. Could you perhaps shed some light on this matter? Is this a joke, a misconception, or perhaps there's some truth to it that I'm simply unaware of? I'd appreciate any clarification you could provide.
