This does not need to be cheaper, it is about choice.People who don't have the funds to buy this device in the first place should not subscribe to that kind of services. There's no way the would be cheaper on the long run, and you can't resell the device afterwards
By your logic that means that 90% of people in life should never buy virtually nay new device/tech etc as they are buying something that is beyond them.
I personally see no issues at all as it is no different to subscribing to Spotify or Apple Music.
This is the way of the world now, subscribing and never owning anything, so we have no choice but to adapt and enjoy.
