Is Disney no longer owned by Winnie-the-Pooh?

Excuse me, but I'm a bit confused by the question. Could you please clarify if you're seriously asking if Disney, the multinational mass media and entertainment conglomerate, is no longer owned by a fictional character like Winnie-the-Pooh? As far as I'm aware, Disney is a publicly traded company, with a diverse shareholder base, and has never been owned by a character from their own creations or any other fictional entity. Is there perhaps a specific context or joke that I'm missing here?
