You're missing the sarcasm.This dumb hypothetical you dudes bring up is stupid. A person on a submarine wouldn't buy a digital console in the first place dummy. How would they even download a game? Do you guys think or do you just skim through it?
"What about people in submarines" is mocking the faux outrage Sony stans had when the XBOX One was revealed and they said it required an internet connection.
Sony stans came up with all manner of super specific hypotheticals to clown the always online requirement which in the end forced MS to fall back and rethink the requirement.
