Weird downvotes! From the source: "Your Content belongs to you. You decide whether and how to license it. But at a minimum, you license npm to provide Your Content to users of npm Services when you share Your Content. That special license allows npm to copy, publish, and analyze Your Content, and to share its analyses with others."[0]

I'm not a lawyer, but in my best judgment I see no reason to assume an NPM package can continue being used after it is taken down -- you need to actually evaluate the license it's published under to determine that. If I'm mistaken, I'd love to see a source establishing the contrary.
