Does not change the fact he rather still subs KyoAni animu that are seem to also being subbed by half the sub groups in existence.
He pull this same stunt with "Lucky Star" not so long ago.
Point ends up what he brings to the table? the only reasons to pick one group over another is the video quality and translation accuracy.
He can troll with PRIORITY! all he wants but in the end we simply only give a shit if he is delivering the goods and he is not.
