Taken out of context, this sound pretty bad, but in context, it looks like he's just joking with/trolling another developer friend of his. Look how he carefully word his replies so that he never actually says that games should always be online and connected to the Internet. The "always on" statement can be thought of as him saying all consoles need electricity, his analogies are purposely vague. His "why would I want to live there" remark doesn't directly insult people who live in rural areas, it just states that he doesn't want to live there. Actually, he later apologized for the indirect insult. This statement was in the article the OP linked to:
"Apologies for offending non-cities, I was trolling [a friend] personally."
If he is just joking, then the outrage over this just shows how public platforms like Twitter are ill-suited for private conversation, and how, when you're an official for an entity with a large public presence, much of what you say will be tied back to that entity whether you want it to or not.
