This article doesn't come across to me as angry, not at all. I would say Marco is more disappointed than anything, especially knowing how good some of Apple's other cloud services can be: contacts, calendars, push notifications, and photos. I would have vastly preferred a clean break from iTunes (i.e., a simpler "Music" app rather than cramming more into iTunes), similar to the way Apple deprecated iPhoto in favor of Photos. The latter has been rock-solid for me thus far, something I could never say about iPhoto.
