And tied to a direct back account, requiring you to use cash and lose any CC benefits. I use Privacy for things I know I only want to charge once (e.g. $1 trials or things of that nature) but not being able to charge a CC with Privacy is a bit blocker most of the time.
I'm saying I get rewards when I use PayPal (because everything ends up on a credit card anyway with added privacy/control benefits compared to using the card directly), so a solution where I don't get those rewards ends up being second-class. I also haven't had issues with PayPal that [many] others have, so there could certainly be a scenario where that changes.
