Maybe not.
I mean, if it's already dirt-cheap service on account of the low quality, maybe Spark's already "paying half price" without actually paying half the price. Or maybe it's not dirt-cheap but there are other factors which make it legitimately expensive to provide reliable service. Maybe Spark lives in an active warzone, and the service provider needs to regularly send out ninjas to repair hard connections. Maybe Spark lives on the far side of the moon, and the internet is only active half the time because it's transmitted by a personal satellite orbiting the moon.
