These subscription models, or even machines that require only a certain type of consumable, are effectively leases. Sure you may buy a piece of hardware, but it is only useful for as long as you buy and use the required consumable.
I am comfortable in renting a place to live - especially since I have moved about every 2-3 years in recent memory - and I am comfortable paying a subscription fee for some software and services. But I am not that comfortable when I have to subscribe to food or clothing for example.
