They are terrible deals for consumers.

You are only going to care about OTP on the flights that you fly on. Your example about transiting at other airport would apply, except the vast vast majority of JetBlue flights all touch JFK and BOS. I guess if you are used to transiting through ATL with DL, you'd care about their ATL OTP. But since JetBlue is either going to get you to Florida or Latin America directly or not at all, the only OTP that matters for you is their OTP on that direct flight.
