Declining Diablo 4 Playerbase Leaves World Boss Events Empty, Forcing Solo Play

Some Diablo 4 players are showing up to World Boss Events and finding no one else there, forcing them to fight alone.
This may be happening because the Diablo 4 player base has dropped significantly in recent months.
Twitch viewership for Diablo 4 has declined from almost 1 million daily to around 13,000 in August.
The lack of players at World Boss Events makes them very difficult or impossible for solo players.
Possible reasons for the player drop include an unpopular first season and competition from other big games.
