This afternoon, a friend brings its Switch with Mario Kart (she have the DLC on this Switch and another Switch at home) and had some message about update and shared DLC.

We actually could not play the DLC because the second Switch on its home was not uptodate and online.

Dunno what it means, but I suspect you could have some surprise if you have no access to your other Switch.

Yes, they previously hire a private detective for Switch emulator dev few years ago and did some intimidation. It’s illegal to do this (at least in EU). A company should use law, whatever reason it is.

I would love to know how this action will ends.
