There are multiplayer games from 30 years ago that still have 30 people who play on the first Friday night of each month, and they will put that in their calendar and keep the game alive.
The idea that multiplayer games need huge communities of players otherwise they are "dead" is what is killing multiplayer games.
Probably because GenX and Millenials (the actual people who created and played these games respectively) don't like being associated with the generation that's destroying our society and planet whilst being completely out of touch with reality. It was boomers who tried to ban these games, remember?
