Ran into this the other day researching a brewery. Google AI summary referenced a glowing NYT profile of its beers. The linked article was not in fact about that brewery, but an entirely different one. Brewery I was researching has never been mentioned in the NYT. Complete invention at that point and has 'stolen' the good press from a different place and just fed the user what they wanted to see, namely a recommendation for the thing I was googling.
