That's not really accurate, you don't have to pay to ride the Skyliner, as Ross mentioned, you can go to DHS to ride it. But Disney is making it a challenge to get dropped off at CBR or RIV to then hop on the Skyliner, just like they do with resorts around MK for those trying to avoid TTC. It's more about lessening the impact of large numbers of Uber/Lyft at resorts by non-resort guests and pushing them to use the parking lots that are designed for it.
