Ah, I thought you were asking me a genuine question, not looking for an excuse to be rude. My mistake for thinking better of you. Nevertheless, i'll reiterate.
As I clarified in my second post on the subject of TBA's foliage, the material being used on much of what is covering the rockwork specifically looks somewhat flimsy. Looking at closeups, it looks quite thin, and the individual leaves/petals flutter and bend in even a light breeze. This compared to the rigid and tough foliage on the Tree of Life. The leaves they've covered in the new cypress trees along the flume also seem to be built out of somewhat sturdier material for the record.
There actually is plenty of fake foliage across property at WDW that is very faded and could use replacing. Even some on 7DMT is already looking pretty worn out. This included Splash Mtn in its final few years, and said foliage wasn't even all that old. TBA will no doubt get to that point as well. And some of what they're using appears like it has the potential to deteriorate more quickly than other cases.
But again, it will be up to Disney to decide how worn out it's allowed to get before they do something about it. They gave up on Splash, and that ride wasn't even an outlier at WDW. One wonders if they'll be motivated to take care of TBA for a change.
