I think it might be like when Grok was programmed to talk about white genocide and to support Musk's views. It always shoehorned that stuff in but when you asked about it it readily explained that it seemed like disinformation and openly admitted that Musk had a history of using his business to exert political sway.
It's maybe not really "caring" but they are harder to cajole than just "advertise this for us."
For now anyways. There’s a lot of effort being placed into putting up guardrails to make the model respond based on instructions and not deviate. I remember the crazy agents.md files that came out from I believe Anthropic with repeated instructions on how to respond. Clearly it’s a pain point they want to fix.
Once that is resolved then guiding the model to only recommend or mention specific brands will flow right in.
How would that matter against the operator selling advertisers the right to instruct it about what the relevant facts are?
