Apple hardware/software, Microsoft Windows, Intel hardware, Netflix (buffet TV shows), Amazon web store (logistics), Etsy store, Steam / GOG Games - all of these (except Netflix) are selling* either hardware or software, to you, once.
Netflix is a subscription to access and stream a lot of shows, but it is "fee for subscription service", not all that different from an alarm company subscription, OnStar, or a subscription lawn maintenance company.
* Ok, Steam / GOG Games or Microsoft Windows is a licensed use with limited conditions, it's not like you can use it on just any hardware
