Notice how pivotal iCloud+ is?
See why they screw everyone on base storage and component upgrade pricing?
Notice how they never bump the included iCloud storage (or add to it per new device purchased) so you have to pay for iCloud+?
Is it more clear now why they offer no paid iCloud storage options between 200GB & 2 TB!?
The iCloud+ "business" is largely a racket
People are getting screwed, by design
I don't quite understand the correlation between iCloud and physical storage.
For example, my iPhone, iPad and MBA all have 256gb of storage. I pay $1 a month for 50gb of iCloud storage, of which I have used about 37gb. Mostly to sync photos, as well as back up my iOS devices. None of which has anything to do with the base storage of my Apple devices, nor is it saving me anything in terms of storage space (iCloud is used mainly to sync data, and they still reside on all my devices, taking up full space).
I am also subscribed to OneDrive and wish that they offered a similar plan to iCloud. Right now, It's a flat fee for 1tb of storage, but I don't use anywhere near that much (current have about 30gb of files / documents saved there). I wouldn't mind being given the option to pay a reduced / pro-rated fee for less storage. Otherwise, you can offer me 1tb or 10tb of storage a year; it's just a meaningless number after a certain point.
It's a similar sentiment with dropbox, which has been getting more expensive (and which led me to drop it for Onedrive).
I don't feel like I am being screwed or cheated in any way by Apple. My needs are fairly modest, and it feels like only Apple is willing to meeting me in the middle. If you are complaining about having to even pay for iCloud in the first place, that's an entirely separate matter, and I am perfectly fine with paying $1 a month for the convenience.
