While that is true, it does divert peoples' clicks.

It's an open ethical question that it's not straightforward to answer.

EDIT: yes people also learn things and repost them. But the scale at which ChatGPT operates is unprecedented. We should probably let policy catch up. Otherwise we'll end up with the mess we currently have by letting Google and Facebook collect data for years without restrictions.
