That's a completely flawed analogy. In your case Seabrooks will most likely want as many outlets as possible, and will lobby/offer financial incentives to Morrisons to carry their crisps. In the case of an airline whilst an airport can facilitate them by way of facilities and financial incentives, it will only happen if the airline decides it can operate the service if it can make a better profit compared to other destinations.
That calculation will include diluting profits from other routes. Deciding not to operate a route doesn't necessarily mean that it can't fill a couple of aircraft a day, and cover its operating costs.
