That was just the Yuzu/Citra team. Main reason they got in trouble (from what I understand) is that they were making money off of it, specifically people had to subscribe to their patreon to get Tears of the Kingdom optimized builds, when the only copy of TotK available was an illegal pre-release one.

There were some more things like messages they sent that were incriminating, but that was the biggest thing afaik.
