There's some validity to both perspectives.
Earlier at least one person said they'd pay for Genie+ but cut the equivalent elsewhere so "Bob doesn't win". I mean, if you pay for Genie+ but buy two fewer churros per day, Disney is getting the same revenue (or more once inflation of prices is taken into account). By all means, do what you have to do to make a trip work for your budget, but nothing will change as long as people keep going.
While I completely agree it's reasonable to criticize aspects of Disney but still go due to what value is still provided, it just feels like most people are really really unwilling to put their money where their mouth is when it comes to displeasure with Disney.
