This whole "it's more accessible" argument is nonsense and disingenuous. There are existing systems in place for that. If you're going to just take the company line, fine, but either just admit that's what you're doing or find a line of arguing that makes more sense. It's not like you're going to get a free Mickey bar for defending the company's bad policies.
It couldn't be plainer what's happening here and why people are upset: Disney's trying to do a bait and switch here by advertising a new ride that people are assuming they will be able to experience the way they've been able to experience pretty much any other ride that's opened anywhere up to this point. Then people show up and find out they're out of luck if they can't play fastest finger on their phone successfully or aren't willing to pay an additional $15.
There is no good reason for this ride specifically to have the system it does. ROTR had it because of unreliability. Spider-Man had to deal with stricter capacity restrictions because of the reopening. There is no evidence that strict capacity restrictions remain in place, it having been established that at this point the reservation system is to help Disney save a buck on staffing moreso than anything else, and MMRR is a proven, reliable ride system with high capacity that has worked just fine at WDW. But because of how DLR is choosing to operate it, the ride is not presently doing what it is designed to do because Disney is using it to try and reach into its guests' pockets yet another time.
Again, it's a recipe to annoy people with little upside for anyone. The $15 Disney will make from some people who cave in and pay for ILL will not outweigh the number of people that're going to be upset because they feel like they've been cheated for no good reason.
