I think this is incredibly subjective. Universal really hasn't done or said anything much different from Disney. I think people that are mad at Disney think Universal is doing "better" simply because they are mad at Disney. Universal Orlando is closed to 5/31. Disney is closed indefinitely. Universal is only "ahead" of Disney if you suspect they will open 6/1. If they don't, then they have led their guests on even longer than Disney, who has been pretty upfront about saying, at least for the last 4-6 weeks, they simply don't know when they will open.
What is worse? Someone saying, "we don't know" honestly, or someone saying 6/1 right up until they don't open 6/1? I know Disney fans got all excited yesterday for 6/1, but that is their fault, not Disney's. Disney is closed indefinitely right now. People on these boards are exceptionally emotionally invested, and so they are lunging and grabbing for any scrap that they can find. So they are extra frustrated when it doesn't go their way.
The people that are exceptionally emotionally invested in Universal are probably going to feel the same way 6/1... Wonder if they will look at Disney and say "man I wish Universal had been more honest, I'm switching to a Disney trip."
