I always wonder when a company does this if it is completely altruistic or if something else is going on behind the scenes. Maybe notifying customers gets them to reactivate, maybe if they resubscribe later they can charge more, maybe it’s better for financial reporting and projecting subscriber counts. On the other hand it could just be a rare moment of a company doing right by the customer.
It could be canny business sense.
It could be both.
in a similar vein, Ikea umbrellas are discounted when it rains.
