I don't think the "every other park is open" argument holds water. The international parks are open because their numbers are much better. Florida is open because their governor is making no effort to control the pandemic. I do not even believe that there's no spread from WDW because it's well known that their contact tracing is a disaster. Newsom cannot just do what other places are doing because his obligation is to the public health of our state. As many people as there are who would be happy to go back to Disneyland or go back to work, most of the state would not be going and does not work there anyway. And that significantly larger population would not be happy about him opening theme parks.
