Yeah because if a game has multiplayer support and that part of the game is still roughly as popular as 9 years ago that means the game has no multiplayer.

What the hell. JJ2 Multiplayer still has a steady amount of players. New levels for it come out weekly. Recently a patch was released that was primarily focused on multiplayer. The amount of battle levels (one of the many multiplayer game modes) uploaded to J2O alone is more than the amount of single player levels uploaded to J2O in total. It is clear to everyone but a complete moron that the multiplayer part of JJ2 is more active than the singleplayer part.

But sure, JJ2 doesn't really have multiplayer. Whatever floats your boat.
