In Japan, when online game services are shut down, users sometimes protest against individual games, but currently, many accept it as "unavoidable." However, from a cultural preservation standpoint, it's undesirable for games to become unplayable altogether.
I think many people would understand that the idea isn't "provide online services forever," but rather "they should be made playable offline." While it's still practically non-existent, Japan might need a "Stop Killing Games" movement.
