This is a simpler version of url-fetch from Guix, that doesn't support mirror:// or file:// uris. It is specifically designed to prevent substitution of the source, for the purpose of downloading copyrighted content you have access to, but you don't have the right to redistribute. By marking the derivation as non substitutable, this fetch prevents you from giving others access to the source if you run a substitute server on your machine.
