That's... a strategy. Matter of time before an AI companion company succeeds with this by finetuning one of the open-source offerings. Cynically I'm sure there are at least a few VC backed startups already trying this
Cynically I think Anthropic is on the bleeding edge of this sort of fine-tuned manipulation.
Also If I worked for one of these firms I would ensure that executives and people with elevated status receive higher quality/more expensive inference than the peons. Impress the bosses to keep the big contracts rolling in, and then cheap out on the day-to-day.
