I agree that "gouging" seems like the wrong term, but it was used once in the title and once more in the article: "This price-gouging annoys Mr. Buffett..." So, we don't actually know if Buffet himself called it gouging. He is quoted as saying he wants his shareholders to not have to pay as much, and points them toward a service that might provide a lower price for accommodations. Seems reasonable to me.
