I like how this article does not talk about the anti consumer practices engaged in by Nintendo, that might push some customers away from their consoles. /s Nintendo can disable your Switch 2 for piracy in the U.S., but not in Europe, as confirmed by its EULA. There is already a switch in my household, but the price along with the ability to remotely brick the device, is what made our household pass on the switch 2. We bought a second steam deck instead.
The point they are probably trying to make is with a key you don’t own the game like you would with a hardware cartridge in older Nintendo systems. So you own nothing on the switch.
And the point I’m making is that only a handful of games are keys; the vast majority are still on the cart, same as the last system.
