It's not a fact. It's Disney's opinion, one that is scewed by wanting the most money from it's patrons. There in lies the problem with so many people, before Disney seemed to balance both. Now they seem to care only about maximizing profits even if customer service and many other aspects suffer.
Again, it has been like this for over twenty years. Is everyone who is complaining people who visited Disney in the early 1990s?
I've been visiting WDW since nearly the beginning. My first trip was in 1976. You way it's been like this for 20 years. To that I'd say yes and no. In my opinion, there was a key change 10 years ago that changed the equation at WDW and led us where we are today. Disney started actively starting pushing for volume of customers at the expense of margins. 2001-2001 saw the aftermath of 9/11. Then in 2004, hurricanes Charley and Frances ripped across Orlando. Disney's attendance was hurting. January 1 2005, Disney introduced MYW tickets.
Dec. 31, 2004, a 1 day ticket cost $54.75 and a 5 day park hopper cost $249 (4.5x the 1 day price) The 4 day park hopper cost $219 (4x the 1 day price). 6 and 7 day tickets were only available as park hopper plus tickets that included the water parks.
On January 1, 2005, a 1 day base ticket Jumped to $59.75. But you could now get a 10 park hopper (that expired in 14 days) for $232(3.6* a 1 day price). That's less money than the 5 day ticket the year before. Disney was "penalizing" you for taking a short trip and strongly encouraging you to take a long single trip.
That next fall saw a variety of specials to encourage people to book during hurricane season. "Free Dining", 7 days for the price of 3 on hotels, tickets, and Dining, were just a couple of them.
If you look before and after than time, you can see a change in the numbers and quality of attractions added to the parks.

Looking at the attractions before and after that date, you can see a big difference. People who who frequent the the table service restaurant talk about the simpler menus and closer tables since free dining has been around.
Of course the trouble is the strategy that saved them after 9/11 and the hurricanes is coming around to bite them now that the economy is starting to improve slowly. They have theme parks at record attendance that haven't had major expansions in several years (outside of NFL at the MK now). And because most of the expansion has been in hotels and DVC they still have massive numbers of rooms to fill every night.
I think what we are seeing now from New Fantasy Land to FP+ is an attempt at a "quick fix" to allow ever increasing attendance into the park.
