A history shutting down unviable services is a glass half full. On the upside, it means they won't permit a service to limp on, viewing its customers as burdens and providing terrible service in the hopes they go away.
In either of those scenarios, migration off their services would become necessary. But if they keep it limping instead of cutting it off, that I think facilitates safer more cautious migration (if for no other reason, because it would give you more time to do so). In that respect, keeping the service limping would probably present the superior customer service experience.
