The question is not that Apple offers 50GB of cloud storage for $0.99/month, the question is why has the base storage not been increase from 5GB to something more reasonable to say 15-25GB. I suspect Apple does this to force users to pay for cloud storage, how many people who are a bit over the 5GB need to upgrade and pay another subscription per month. Everything is a subscription these day, to provide the illusion of a lower cost of entry.
I paid once for cloud storage and dislike subscriptions as much as possible. It’s bad enough that I have to pay utility bills every month, now I have to keep track of minor recurring costs. I can see why people are tired of this model and businesses love them, people will blindly pay those minute amounts and think nothing of it, while all these small amounts add up to a company’s bottom line.
Remember Office Space the movie with the rounding “bug” from every transaction.
