>nail in the coffin

> is .. all people want.

Try making more measured statements, you exaggerate your point and end up being wrong. Of course this new barely used product feature is not all people want. Of course this minor product feature is not the nail in the coffin of whatever argument, they are just responding fast to a smaller competitor by providing that feature themselves, something that happens thousands of times in business, did Instagram prove it was a commodity when it implemented reels by copying tik tok? Did Uber prove it was a commodity when it started offering food delivery? Doesn't make much sense.
