The forced “employee-owned coop” narrative is clearly just Disney apologizing for their own story. In order to justify the ride’s elevation, they made it a salt mine, which meant Tiana couldn’t just own a restaurant, but an entire food empire.
But of course, making Tiana a greedy capitalist executive would go against everything they believe in at The Walt Disney Company®, Inc. Corp. LLC. So they have to overtly advertise that Tiana’s Foods does not follow the traditional oppressive corporate structure.
The issue here is not that the company is “employee-owned.” It’s that Disney feels compelled to tell us that and advertise it when it has no bearing on the story. I haven’t seen any signs advertising the number of employees at the company or whether they have casual Fridays, for example, because it would be irrelevant and out of place.
