That article reads like it was written by AI. Feels like a ChatGPT bullet list just with the emojis deleted. They also didn't really say much specific about the FOSS dev burnout, just generic explanation about what burnout is. The article cites a study but then instead of talking about things from it, it just says generic slop about how a burned out FOSS dev could feel.
Edit: I feel like my comment contradicts itself but it's hard to put into words exactly what's wrong with the article but it just reads so poorly.
