You're not wrong, but I felt these words of caution are something anyone should be aware of should they pursue TFA's advice.
If you're doing it for intrinsically valuable reasons (i.e., for yourself), wonderful!
But if you're doing it to try to overcome writer's block or establish themselves as a recognized name in a community, there are downsides that people don't tend to talk about much because they might sound ungrateful (especially if they financially benefit from their popularity). I, individually, have no such monetization incentives at play.
