It is nakedly obvious that WDW currently, clearly prioritizes ALL attractions that have FP/Genie/whatever over those that don't, and has for some time. In doing so, they have, intentionally or not, devalued EVERY attraction that doesn't have FP (please forgive me for using FP only from this point onward, it's just faster that way). When so many things have FP and so few don't, the message clearly becomes to the guest that the FP attractions are the ones that 'matter' and the ones that don't have FP are just filler. And there's no way WDW, with its survey wizards, doesn't know that. If it cared, it would have done something more to attract an audience to these shows instead of being like "oh yeah, we also have..." with these attractions as they have over the past decade.
If you want people to value these attractions, you don't so transparently treat them as the second class citizens of things to do in your parks, for people who aren't quick enough/smart enough to nab the FPs for the attractions that sell themselves. If your actions as an operator are subconsciously telling guests that these are lower tier experiences, or experiences of lesser value, that's how they'll treat them. When's the last time they made a serious effort to market these attractions, or feature them as anything other than "oh, these are historical" for five seconds in a documentary? To even try to center these attractions in the conversation in ANY capacity? They haven't. Through their actions, they've as good as dismissed them to the average guest, and then act surprised when people don't treat them as worthwhile things to see.
