The storage price isn't really an issue. For the average game it's probably $2 of storage on a hard drive when it's not currently installed on your console. And digital versions see discounts more often.
I'd say screwing up ownership is a much bigger issue.
I remember when the ps3 released Sony mocked controller rumble as a 'last gen feature'. Now their haptic feedback is the only distinguishing feature of their console.

Now at a time when memory and storage prices are at an all time high - they pull a move that directly hurts the customer.
