Perhaps it hinges on the definition, or perspective, of contained and uncontained. From the perspective of the plane itself, the Maastricht failure was 'contained', and therefore less newsworthy. (?)

Most gas turbine engine failures are “contained” which means that although the components might separate inside the engine, they either remain within the engine case or exit it via the tail pipe. This is a standard design feature of all turbine engines and generally means that the failure of a single engine on a multi engine aircraft will not present an immediate risk to the safety of the flight. Sizeable pieces of ejected debris may, though, present a hazard to persons on the ground.
However, an “uncontained” engine failure is likely to be a violent one, and can be much more serious because engine debris exits it at high speeds in other directions, posing potential danger to the pressurised aircraft structure, adjacent engines, the integrity of the flight control system and, possibly, directly to the aircraft occupants.
