You're delusional if you think it's for archiving. I don't even know what you mean by that, as in archiving ROMs online for posterity? It's clearly for emulating their games with pirated ROMs.

I completely understand it too because I've been pirating since games were on tapes. But, surprisingly perhaps, I have the ability to view things from multiple perspectives. And clearly Nintendo don't want their titles to be pirated while they're still making sales.

At some point in the future, just like with GBA and SNES emulators, I'm sure we'll see the same for Switch emulators.
