It is nothing like the setup MS proposed. You can still chuck a game cart to a mate and them play it.im not sure why the outcry isn't as bad as when xbox said you can't game share. its the same EXACT premise. possibly because hacking is involved? maybe...
some call it piracy, i consider it game sharing. someone has a copy, they offer for me to play it and i do, since i don't "own" it, im now banned. i guess they are mainly attacking non-legit certs for games and downloads that don't originate from the system, but what happens if Nintendo makes a mistake on their end with the cert detection? how they gonna recover that one?
im for banning online play for the user ID, that makes perfect sense. they don't want to muck up their online environment.
I would like them to have a robust online reselling, lending and whatever platform for their downloaded content but that is a different discussion. If you wanted to say you created a setup a la https://gbatemp.net/threads/this-si...e-2001-and-isnt-afraid-of-nintendo-co.515799/ or you sold an account with some games but for this then maybe I would have some sympathy, that is not what you described though.
Similarly what does banning an ID do? 5 minutes to make a new account? Whoo. Maybe you have some fools that value achievements and trophies enough to consider a ban a problem. Maybe if you ask disabled all other saves on the account (in which case default practice would be to have a throwaway and a real account, or a new account for each save). An account ban is barely a slap on the wrist.
