They are targeting exactly one person that they are in litigation with. I am shocked that Kotaku would misrepresent something in the lede and then contradict themselves later.
However, because Williams allegedly evaded Nintendo’s attempt to serve him, and then didn’t appear in court, Nintendo argues in its filing that this meant they were unable to find these identities through discovery, and as such is seeking the subpoenas. The company, currently worth $67 billion, says these will be “limited in scope,” designed to identify “the account holders and the sources of any payments made, and where applicable, aggregate traffic and access statistics for Pirate Shops’ websites and related online locations.”
TL;DR: Stop trying to make money from piracy. Dolphin is alive and well after 20 years of emulating Nintendo products. Not sure how people aren't connecting the dots with what Nintendo chase and what they don't.
