Even Disney and Universal don't view it that way. Everyone likes to bash "blue ocean," but "blue ocean" is real. You don't need to beat the other guy in your market, just grow the market.
Hardly.
That's what they may say publically. Like when a sports team compliments their opponent. But you're crazy if you don't think there have been plenty of closed door meetings of nervous execs talking about what's going on down I-4. They care about every dollar lost to competition. Especially when competition is trending up at a rate such as Uni has been for 2-3 years now, with more expansion planned. They're not going to lunch together and high-fiveing.
Proof of this is Magical Express. Hundreds of thousands of dollars (at least) per year at no additional cost to the rider (yeah, yeah, it's in the cost of the hotel room) designed to make it simple to get to Disney property and very difficult to anyplace else.
Proof of this is Free Dining. Millions of dollars per year in free food and drink given away (yeah, yeah, it's in the cost of the hotel, etc) to entice those that are on the fence about Disney to not only go, but also spend extra dollars to stay on-site, at which point they receive free (lol) food and drink, making it much less enticing to leave property.
Proof of this is Magic Your Way tickets. They get cheaper the more days you add. It can be a tough choice for mom and dad and their two kids... Do we add two more days to our tickets at Disney for a total of $120 (or whatever it is) for a family of 4, or do we go buy two day park hopper tickets at Uni for $959, plus spend money for food and drink there when we already have the free dining plan at WDW?
Proof of this is the over $2 BILLION dollar cluster known as MyMagic. Designed to squeeze more blood out of the turnip, by Iger's own admission. Billed as a way to "leave your wallet in the room". All meant to simplify (and data mine) your park-going experience and deter you from leaving.
I'm quite sure there are other ways they work to keep people at WDW, but those are the four that instantly popped into my head.
Those aren't designed because TDO is content with losing double-digit percentage revenue to Uni.
