I think they are MOSTLY incompetent and SLIGHTLY lying

Please feel free to add your own theories!
Too hard on Mt Gox, you say? Well, consider this... If Mt Gox couldn't handle the influx of new users, why did they only experience problems when bitcoins were going down? The volume didn't seem to bother the site one bit when bitcoin prices were skyrocketing.
I %100 agree with you the btc community needs to find n start other exchanges so mt gox doesn't get away with this Anymore
