ROM sites are different in that they are distributing the copywrited media
The only 'emulator' cases I've seen be successful are due to the same, they didn't get in trouble for the emulator, they got in trouble for distributing ROMs. I wonder if there's some firmware code being distributed here? that's a common annoyance when it comes to using an emulator.
By "online" do you mean a random ROM website, or any Yuzu provided/hosted/whatever page? I.E. are they linked to such firmware and key redistribution? I was under the impression there was no affiliation, but I may be wrong there.
By affiliation I mean something like hosted on the same server but officially unlinked, not obvious affiliations. If a core maintainer redistributing them on their personal website.
