It is kind of annoying that Irdeto, the makers of the oft-maligned Denuvo DRM, have made one that specifically targets Switch emulators, even though emulators are legal.
I would 100% pay $70 to buy Zelda that just runs on PC at 4K...but nope, gotta have it at 720P @ 28FPS.
It's a bit hit or miss on other consoles, but it's often pretty straightforward to dump your own games. IMO, it's kind of dumb to make people "do a little dance and magical incantation" to make what they're doing "more legal" especially when there's little case law about it.
Also, everything on the switch is ID-tagged. If nintendo wants to, they can ban carts, consoles, controllers, accounts, and more for arbitrary reasons.
