A lot of people are saying they're just going so they can make money off of it. But they make money off of it by having gameplay that is fun to watch, activities people want to do and need help with, reveals of new things to do and find, showing efficient ways to grind (only a request if there are actually things to grind for), and making lore videos based on a deep lore system. The ways the people who do just want to make money off of it still lead to improvements for the average player. If people who no-life the game for their stream have ideas on what could keep them playing, that translates into more than enough for a regular player.
