I thought they were sharing Nintendo encryption keys that are "technically" supposed to be from the Switch you're emulating. People were using Yuzu to turn their Steamdeck into a Switch and using Yuzu's private discord to get the keys needed to do that.

It's the same reason other emulators ask you to bring your own BIOS file because that is proprietary.

AFAIK, they were explicitly not sharing those keys. You had to get your own. They provided instructions on how to copy them from your own hardware.
