Google doesn't sell its search feature as a product that you can just plagiarize the results from and they're yours. Microsoft does that with Copilot.
Copilot is as much of a search engine as Stable Diffusion or DALL-e are, which is to say they aren't at all. If you want to compare it to a search engine, despite it being a tortured metaphor, the most apt comparison is not to Google, but to The Pirate Bay if TPB stored all of their copyrighted content and served it up themselves.
