Still piracy, it has to be from your owned physical copy.An interesting point I did not know.
Possibly an ethical discussion for another thread: if you buy a physical version of a product, are you then entitled to pull a rip of it from the internet?
I'm assuming a person could borrow another person's Switch purely to rip the game they purchased correct? With the Switch selling so well it's not like it would be hard to find someone to borrow one from.
