I could be wrong, but I thing the idea is that Twitter is immune to censorship, so no matter what sites get taken down, file sharing can live on in 300 baud. Or something.
Well, it does say "experiment". But I think the point is summed up in this line: "I believe that piracy will always exist". The OP is showing that data is so malleable that no matter how many Megauploads you take down, there will always be a way to share it, which seems obvious to us at HN, but to a layman this might be a little more eye-opening. Or maybe he was just fucking around over the weekend and wanted to find the most ridiculous possible way to send data.
