Yeah, the guy comes across as a massive [expletive] in that article. It reminds me of the piratebay "F U" emails from decades ago. It seems to me that a lot of Americans or American Companies (and Swedish pirates) ignore other countries' jurisdiction.
Edit: just reading into this and New Zealand apparently wanted to take legal action (up to ten years in prison) against any New Zealand citizen who simply watched the video on Kiwifarms forums? That's astonishing.
