What about the Sony hack required extreme sophistication? Placing tailored screens on all user desktops, the way the data was found and exfiltrated.. it all might not have taken massive skill, but there was a lot of time, effort, and planning involved. North Korean IP addresses mean nothing. My VPN provider allows me to have a north korean IP address, and hacking into other north korean systems to use them as jumping off points is not overly difficult. As far as your motive question, this can only be answered with speculation.. but I mean even the us government had a larger motive than NK. NK not only did not prevent the release of the movie, they made it more popular, and they got no money, profit, or benefit of any kind out of these actions. At the time the attack happened the largest story in the news was the upcoming release of a CIA torture memo which detailed the horrifying abuse and torture of a large number of people. There was a large back and forth in congress about the release of the memo and the damage its release would have on the country. The Sony hack happened just before the memo was made public, and the Sony hack consumed the media news cycles and the torture memo was swept under the rug for most of the general public. I feel most people don't even remember the torture memo release, while everyone remembers the Sony hack. Now, granted, there's no way to know anything for sure, but you wanted speculation about motive, and I would say there's more options that could fit the scenario than just assuming NK is responsible.
