"What's the catch" có "catch" là cái bẫy, mưu kế lừa người = cái bẫy là gì -> cụm từ này nghĩa là sự việc này có uẩn khúc, thường được dùng để hỏi vặn khi sự việc tốt đẹp đến khó tin.

Ví dụ

So the U.S. Court of Appeals (Toà án cấp phúc thẩm) for the 11th Circuit (khu vực) ruled it was unconstitutional (trái pháp luật) to force felons (người phạm tội) to pay all their financial obligations before allowing them to register to vote, but what’s the catch?

So, you might be thinking to yourself, "What's the catch?" The good news is that there's nothing out of the ordinary for a gaming laptop in the $800-900 price range. According to a review from NotebookCheck, the display panel isn't best-in-class and the RAM is only one stick of 8GB, but there aren't any surprises beyond that. The 256GB SSD is definitely on the small side, but both that and the RAM can be easily upgraded later on.

That’s a lot of good stuff, but remember, there’s no such thing as a free lunch. So, what’s the catch? Well apparently, there are quite a few, something that Zoom CEO Eric Yuan has publicly acknowledged and apologized for, himself. The bigger concern is, as the platform is being subject to more and more intense scrutiny (xem xét kỹ lưỡng) — since popularity also comes at a cost, obviously — more and more loopholes are also being discovered every other day. Some of them may be minor, some catastrophic (thảm hoạ).
