It's virtually impossible for somebody to get charged an unexpected amount. Sure, there are lots of fine print to the service that Apple drew out for the benefit of developers, but as far as an end consumer is concerned, the value proposition is very simple: iCloud keeps all of my devices in sync for free. That's it. Very rarely, if ever, will somebody actually hit one of the edge cases where the syncing does not work as expected due to one of the above limitations. Even if this does happen, they won't be charged for it. If I want to backup my own pirated music, it'll cost me $25/year. That's pretty simple to understand. If I agree, then I will be charged a flat annual rate. There's no way for an unexpected charge to show up with this sort of pricing model.
