So that they can get some goodwill from a Full Fare J Class pax on a route with a lot of competition AND get goodwill from a QF Plat FF on a Y tickets AND they can then sell another Y ticket (which is more likley than a F ticket) or not bump someone AND use up some contingent liabilities in the form of upgrade certs!
