WDW needed FP+ more, as they had the worst guest increases to rides available of any resort.
TDL is pretty bad, and runs out of FPs around noon, but they keep building big rides, and ADDING capacity.
Instead of adding capacity, WDW decided to ration rides, and add minimal new rides for 19 years, sometimes just replacing others. They got away with it for a while, but the problem festered, and grew until they faced a crisis, and had to announce ridiculous amounts of investment two years ago at the last D23. And maybe a ton more investment announced today.
