Oddly enough, this comes from Google having a monopoly on web advertising. If you're an advertiser, let's say for the sake of argument you're a company with $80 billion in revenue, and you find your ads placed next to a ragebait post, you might complain to Google, and they will promptly send you a canned response and send your email to Gemini for use in training data. If human eyes ever chance to see your email, it's a good chance that people in that department aren't working hard enough and they should do a layoff.
