What kbart means is; if the DRPK/Korea link came later this flies against the fact that before anything else it was compiled on a PC with Korean locale.
That still doesn't present a contradiction. The post says that they didn't latch on to "The Interview" until after the media linked it. That doesn't mean they weren't doing things to make people think it was coming from Korea.
Yeah, especially because the Korean link was probably what started the "The Interview" saga. Not really a contradiction.
