It was always just blue sky art they quickly pulled out to protect Disney+ from boycotts during summer of 2020. The tree destroyed sightlines, weighed too much, the attraction was never built to support such a thing, and it would have been a major issue to maintain.
I've been reporting on this for months. They went to Avery Island to try to create some sort of backstory for all of this. For whatever reason, they were impressed by the salt dome. Allegedly they wanted to turn the whole mountain into a salt dome background but the budget looks to have limited them to a few fake trees and a garish tower.
Crippled by its own need to present Tiana as a CEO.
Never doubt the power of an agenda and incompetence.
