I can see where you're coming from on that.
I have the FP+ deck that the board of directors saw before approving that project. The entire project's justification really seems to be entirely based on improved guest satisfaction and park ops efficiencies with virtual queues.
In fact, the word "revenue" only appears once in the document, in a discussion about ... refillable sodas:

This slide is a pitch from Food and Beverage division as an extension. Not the reason Fastpass moved to Fastpass Plus. That was more to utilize the tech and further increase revenue. Fatpass Plus was already happening as it was Fastpass going digital. This part of the presentation was essentially a pitch of what Food and Beverage could gain from themselves going digital. This is why you see it labeled an extension, rather than a pitch of what Fatpass Plus is. Two different things. Fatpass Plus itself was not what was being pitched here. Having guests virtual queue was already a money making thing since Fastpass started in the late 90s. That was not under approval and this was food and beverage pitching a further slice of the next gen tech.
It also furthers my point earlier that they could put vending in the queue, but there is better revenue in not.
That is really the issue here and back to my point. Disney sees more value in people walking around and spending money once they virtually wait.
The Food and Beverage put that in there to increase their potential at getting a yes.
