WTF - Rest in peace... I hope no one has to pay any legal fees. Wish you all the best!
As the article mentions, they're releasing the Switch successor soon. I suspect the real reason for this push is to try and scare people off from developing an emulator for that one, at least during the lifetime of the console - it's a bit late to try and kill Switch emulation given that nearly fully-functional emulators already exist.
