The whole "the money goes to Cover, not the talents" argument is retarded anyway. A fat chunk of the money that Cover, and any successful corpo, makes from anything gets reinvested back into the talents for a myriad of things, including events like this. Nevermind that, while making money doing what you love is nice, these kinds of events are more about these talents having the opportunity to be able to do these events. Suisei's goal of performing at Budokan wasn't to make a ton of money from it. It was the experience of being able to perform at such a place.
I know I'm just echoing what plenty have already said, but seriously, if these fags want to pirate the shit, then go for it. Trying to make some sort of moral excuse for it like this is just retarded as hell.
