In some cases the disc locked content is because it wasn't finished in time, although some of it functions fairly well it tends to get unstable due to it obviously being unfinished. Although I recall Bioware and EA getting in some deep shit when the DLC companion Javik was fully usable with almost no issues after Mass Effect 3 was released.
