It's been around for years now, as have several others relating to other airlines that FR compete with.
I was told by one of our contract captains a couple of years ago who had previously flown for FR that he had arrived in Pisa with an aircraft that had "arrividerci Alitalia" on the side. The refueller refused to fuel that aircraft, which had to depart to Genoa in the hope of picking up fuel there before proceeding en-route.
