I am not sure which heartless comments you are referring to but what I do see is genuine concern for the mental health of individuals who seem to be overly attached, on a deep emotional level, to an LLM: That does not look good at all.
Just a few days ago another person on that subreddit was explaining how they used ChatGPT to talk to a simulated version of their dad, who recently passed away. At the same time there are reports that may indicate LLMs triggering actual psychosis to some users (https://kclpure.kcl.ac.uk/portal/en/publications/delusions-b...).
Given the loneliness epidemic there are obvious commercial reasons to make LLMs feel like your best pal, which may result in these vulnerable individuals getting more isolated and very addicted to a tech product.
