I have anecdotal stories about aa friend corroborating this. He had been rebuked and experienced an unwelcoming response on Stack Overflow in response to his questions while trying to learn web development, and found ChatGPT a great teacher in comparison.
I'm a very experienced developer. Sometimes I have questions that are easier to ask a person than go dig through miles of documentation. I could easily frame a question correctly to get a response but even I feel extremely unwelcome there. I couldn't imagine being junior.
