Agreed. I also think on avarege you are injecting much more personal data when using LLMs (from which ads can have crazy levels of profiliing). Just because we do not see ads now, doesnt mean they won't appear one day.
That feels creepy enough to discourage people from using it. If they don’t self-regulate what they can do with that level of personal data, we’ll see laws passed in states like California and then adopted by others.
