It's like some people forget you can cancel your preorder. If you don't enjoy the open beta, cancel it. It's not that difficult. Also another thing to point out is that pre orders aren't going to change development on the game. This isn't a kick starter; Destiny 2 is likely finished and being polished currently or they're putting the final touches on it. They're not going to go "well, we didn't get x pre orders, let's cut this part out for DLC. "
