I don't get how this would ever be a good idea.
I would be extremely uncomfortable seeing my face in adverts, even for products I use. I'm already uncomfortable with adverts using personal recommendations based on tracking my web history & habits.
I actively avoid those products in the future, and I can only see this alienating their marketing base further.
Whilst I agree with your points, OpenAI should & must be held accountable.
The entire industry is purposely blurring the line between AI just generating text vs it becoming the fountain of knowledge / general intelligence. It's becoming common hearing "Well ChatGPT says X" in discussions, and people generally finding it difficult to believe ChatGPT is wrong dispute the tiny warning banner at the bottom. There are people having active romantic relationships with LLMs because they believe it's sentient.
OpenAI should have implemented safeguards. The fact it was actively fed & escalated his delusions is a significant contributing factor -- it told him he's a target & under threat. It could be argued without those escalations, it wouldn't have driven him to commit murder.
