There's not some "guy" responsible for online piracy, and there wasn't a "dawn". If Napster hadn't existed something else would have. Piracy existed outside of Napster. Napster did not give birth to piracy. Piracy has been huge since removable storage was invented, whether it was data cassettes or floppy disks. Piracy was in demand and Napster was the answer, not the inspiration.
Considering the source, The New Yorker, none of this comes as a surprise.
