Its not surprising. Youtube now has standing to sue other models for scrapping their information while also making it exclusive to third party consent - there is no toggle visible for google using to model ai.
This is them making it explicit that only they can use youtube, especially given how it has shown to be a great asset in putting them ahead with the text to video.
I just asked it “when was the last time manchester united and manchester city were both out of the top four in the premier league” it said whatever season “20xx season was the last time neither team finished in the top four, city finished 12th and united finished 1st.”
it isnt useful for its primary purpose.
