It's interesting that in the lawsuit mentioned in the article, Google's defense was that they can't separate the AI overview from search as they are one product. That's almost the exact same argument Microsoft made in its antitrust defense about bundling IE. They went so far as to shoehorn IE into all kinds of system processes that were fine without IE before. But their argument didn't work and they were forced to offer the option to remove IE. But ironically, now the same argument is working for Google, despite the obvious solution of just having a setting to hide the AI overview.
