Longer duration is already cheaper. So not sure why it should be even cheaper
Supply and demand.
To be more specific, the supply is potentially unlimited. What matters is how much of it is sold, as that then funds the game and keeps the good legitimate. By altering the price of the good to be lower, you increase its demand - and since the supply is unlimited, any number of people can buy it up and give tons of money to the seller. Since the item is digital/virtual in nature, the only dictating factor in the success of this sale is whether the amount purchased by a much larger amount of buyers than usual ends up gaining more profit than the small amount of buyers that would pay for the service at normal price anyway.
This is the same philosophy when it comes to a yearly price being discounted per month overall compared to lower prices: it's incentive to generate as much money as possible over a duration by sacrificing a small amount of potential profit which could have been gained by keeping the same price-per-month but would have been less desirable by the consumers.
The same thing happens with Black Friday in the first place: companies sell their excess stock at much lower prices in order to get a large profit with the goods they generally did not sell well or well enough. But since Subscriptions are virtual and thus have an unlimited supply, a company could gain an even larger amount of money from that item than a company would by selling an item with limited supply (as once that supply runs out, they can't gain any more money from the binge).
