And I could name a half-dozen US government -.gov - websites that are downright terrible with respect to usability and security practices. Since when does Nintendo represent all of Japan?

I feel like Nintendo is better than average for a Japanese company tech-wise. But it is notable how they treat the internet; they updated Animal Crossing Switch to add a few new online features, but if you try to use them you have to go through a conversation with a cute animal who basically says "to use this service you MUST agree that EVER GOING ONLINE means HACKERS will LITERALLY KILL YOU and you're only doing this because you're AN IDIOT".

You cannot compare governments to large gaming companies. Nintendo is known for creating amazing quality products… except when they go online.

It's more fair to compare them to other gaming companies.
