There was a Japanese visual novel in the 2000s about a girl who was your personal maid, and was so devoted would always take your side in any conflict, accept and support you just the way you are, even if you were a horrid person to your friends. It turns out she was a ghost, or a kind of yokai, or something. Anyhoo, back on 2ch she attracted a fandom, and there was a second group of people on 2ch who labelled her a "useless person manufacturer" because if you actually had a person who always accepted you just the way you are and never pushed back, that can be actually a trap that prevents you from developing.
It's a theme that's relevant today when people have AI servitors that always glaze them. It puts even certain utopian AI fiction, like Richard Stallman's story "Made for You", into a whole new light.
