This is not the first time I am reading this.
My opinion is that there is no way anyone that has more than 2 brain cells would base their WDW decisions on what is happening in DLP. This is apples and oranges. WDW is 4 parks+2 waterparks, so many resorts and transportations options. Paris is 1 park (and a half if you count the studios

and basically no other options around, 6 hotels from which you can walk to the park, 1 that requires car transportation and no waterpark (unless you go to Village Nature which is not Disney even if there is a joint venture).
People fly to Orlando for entertainment / theme parks (WDW, Universal,
Legoland etc), not to visit Orlando.
Poeple fly to Paris to visit Paris, only pure Disney fans add a DLP visit to their trip.
Most of DLP visitors are either French (around 44%) or Europeans (53% are British, Spanish and Dutch). Only 3% left for US Canadian or Asian visitors. Average stay is 1 to 3 days max. Spending habits of Europeans cannot be compared to WDW visitors.
