And I have little sympathy for elitist thinking. Surprised you didn't bring up the 3 coffees/year comparison.
It's not about the $12/year but the principle of when you buy an expensive Apple device, that BASIC backup should be provided for free. As someone else suggested, there should be a free threshold for each device purchased, I personally think it should be 10GB per Device, to enable basic backup. So if you have an iPhone, iPad and a Mac, you should get 30GB of iCloud, then incremental paid-for tiers in 100GB increments. 5GB was never enough since it launched.
Either that or the Onedrive model where many PC manufacturers offer 1TB free for the first year.
As you correctly state, we already spend much $$$ on Apple's increasingly higher priced devices and more for carrier service. It all adds up, but throwing this attitude around of what's another $36, is just plain arrogance.
Not all of us can afford $100+/month carrier plans, I have BYOD data-only plans for a fraction of that.
Basic backup IS provided for free..plug your phone into any computer and you can back it up. Same goes for photos, documents, music, etc. Apple isn't forcing you to use iCloud storage if you don't want to.
None of the competitive cloud services are free and if you compare pricing, you'll find they're all pretty similar.
