How do people feel about sites from where this data is coming losing out on revenue?
When Google started showing answers, I remember complaints regarding Google benefiting from the site's data while depriving the site of a visitor. ChatGPT takes it to the next level.
Social media companies had run into issues for showing og tag content from news sites, where news sites complained of loss of revenue. In some jurisdictions they were fundamentally forced to ink deals with news sites for something core to the web, which is hyperlinking stuff. Here, we are going one step ahead by summarising.
While we are appreciating this now, this will become a fundamental issue in future if search engines keep becoming the content platform themselves.
