Don't some games have testing though that aren't paid testing? Pretty sure I can sign up to beta test for WoW (when they have something ready) and I wouldn't be paid. *shrugs*
I totally get that the game changers aren't getting paid, but they are getting the game earlier than everyone else so why not let them have it just a little bit earlier and they can test it. They don't have to force them to do it but I bet a lot just would anyways, for free. So long as they still got to record and use the content to make videos after all the embargoes are lifted.
