I understand your point but I think it's misplaced here. This kind of criticism made sense with the Bing/Sydney stuff, since "Bing claims to be self-aware" is misleading compared to "Bing inconsistently recites some sci-fi cliches." People like Kevin Roose were actively spreading misconceptions about how LLMs work. It would have been nice if they had taken your comment seriously in 2023.
But this is different. The subtext of the headline is clearly "Facebook's dumb chatbot had a very dumb glitch." I believe laypeople would immediately understand the AI is just plagiarizing a Facebook mom. Policing the language here seems more about pedantry than correcting actual misconceptions.
(You might say that some people would read this headline and jump to a Her fantasy, where Meta's poor AI is desperate for human connection or whatever. But these people are not going to be swayed by technical accuracy. They will just interpret language like yours as euphemism and denial.)
