I think it's just a matter of trying to be smart about business. Before we get involved in a deal with someone, we have to be diligent and make sure we trust the people we're dealing with. It's not really an issue of being innocent until proven guilty, just making people earn our trust.
But even when we do that, as in ANTI's case, we still have no guarantee that we won't get burned. Twice I have entered into business partnerships with people that seemed honest, and then took me to the cleaners. It happens. But if we let these kinds of things stop us from persuing our goals, then we will never be happy.
I say we should protect ourselves as best we can, and then go all out to make something happen. It's kind of like some writers who are so paranoid that they won't send anyone a demo of their songs because they fear someone will steal them. Sure, it's a valid concern, but you will never do anything with your music if you keep it locked up in a drawer.
We will all be disappointed at some point, but the biggest diappointment I can think of would be that we never even try to achieve our goals because we are afraid. That would be the disappointment that we would die with.
