Online storage service Dropbox is commonly used by iOS developers as a way of allowing users to share files created within their apps to other devices.
Dropbox's latest SDK has incurred the wrath of Apple, because users who don't have the Dropbox app installed on their iPhone/iPad are instead pushed to Dropbox's website via the Safari browser. Here, they can click a link to the desktop version of the service, which allows them to buy extra Dropbox storage without Apple taking its usual 30% cut.
"Apple should reject all web browser apps because they can take you to a page that lets you purchase stuff," writes one infuriated developer. "Go Apple! Crack down on all commerce!""
