This is supposed to be a bad thing.. why are you accepting this, instead of improving? You may call it technology intelligence, but really it is human stupidity. At what point do you stop pulling code you yourself will never check? Have you heard of the recent colors.js case? Will you also pull in a library to add two numbers? Where do you draw the line?
A ludicrous slippery slope, particularly given that the original statement said little more than "other people might have made things that you can use." They can draw the line wherever they damn well please.
