Exactly. If I may use your post as a jumping off point… The underlying problem that existed for years over the course of at least 3 systems but maybe all 4 still exists.
In order for X, Y, and Z poster on this board to get 8-10 attractions on Genie+, all the headliners, or whatever is being put out there, it means somebody out there was getting less and somebody out there was missing out. There’s a finite and too small amount of desirable capacity to go around, no matter how it’s sold and distributed. This is best displayed with Disney’s own Genie+ disclaimer, that you could expect to get 2-3 attractions.
The various ways they’ve packaged it over the years change what kind of park guest can get the most out of the system, but there is no system in which everybody or most can get ‘more’ than another system.
