You can normally see this kind of honesty from Japanese devs. Ubisoft isn't doing anything new, but at least they're acknowledging the issues.
Regarding whether Sony/MS should be accountable, the answer is no. Their only responsibility is to make sure a game doesn't crash/intrude on other running software, and enforce any other rules they set in place in order for a dev to pass certification. Anything else is all on Ubisoft.
Thanks for the interview Patrick! I'm happy that Giant Bomb covers FGC stuff, especially now that Max McGee is no longer at GameSpot, and I don't think they're going to have any more fighting game features.
