No. Universal didn't want freeloaders using the Freestyle machines. That's it. That's why the water option is gone. They would like for Coca-Cola to reprogram the machines so they can make water available again for guests that have paid for access to those machines. If Universal only used Freestyle machines, WHICH THEY DON'T, this water restriction be an issue. If Universal decided to eliminate free water access everywhere, WHICH THEY DIDN'T, this would be an issue. Ultimately, you're only being slightly inconvenienced and you're blowing it up into some crisis that Universal wants everyone to dehydrate and quit going because they made a decision to restrict SOME access to an amenity that is still available to everyone.
And don't give me the sky is falling crap either. We have no reason to believe that this is some harbinger of nickel and diming to come. If, and only if, this start becoming a pattern, we can look at the road Universal is going down. For now, this was a singular decision made to appease guests that were paying extra for access to a machine and were not happy that freeloaders were diminishing that experience for them.
