Because it isn’t a lie. Companies need to justify why they are retaining personal information after they stop using it. If they can’t justify it, they need to delete it.

And you think Sony is going to put their neck on the line to try and argue that keeping old unused accounts open is a justifiable reason? They have literally zero incentive to do so, and a large profit incentive to delete accounts as soon as they can reasonably argue that they are too old. Because that will push people towards re-buying games they already purchased once before.
