agreed, but the original article seems to indicate that apple does have a method in place for merging accounts. if so, the question becomes why would they not allow their non-aol customers to take advantage of this?
to force customers to double-dip on purchases? conspiracy theories welcome.
No method for merging accounts. There has always been a way to re-name accounts (change the primary email address) - that's closer to what's being done here.
Back when this all started, the idea was that AOL members could use the same screen name and password for Apple as they used for AOL. Nice convenience, but done in a much simpler, more naive day. At the time, it was mostly about AIM, and AOL's user base was bigger than Apple's.
t.gillespie is on the money here. And it's not just a matter of what has to be done to merge, but to un-merge, should the merger be the result of an unauthorized account take-over, or just a bone-headed move.
iTunes Store created a situation where a family would share a single Apple ID in order to share the purchases. For most every other kind of service, it's far better to have each family member have a unique Apple ID - their iMessage/FaceTime identities, email, their iCloud data, etc.
Family Sharing is the closest we're likely to come to merger. That keeps the individual purchases "owned" by the original purchaser, and any time they are to be un-shared (when kids leave the nest, or "'til death do us part" turns out to be overly-optimistic), it's a matter of removing a person from the sharing account. While it's not directly related to this AOL move, it's essentially part of the same initiative - get everyone on a personal Apple ID.
If a person with different Apple IDs for iTunes and iCloud wants to merge them, the better solution (from Apple's standpoint) is to migrate the iCloud data to the iTunes Store account. That keeps the licensing issues with the developers and record labels "clean." If the iTunes content is being shared, then the "right"solution is to keep using the iCloud account, add a "new" iTunes/App Store account to that iCloud account, and use Family Sharing in order to maintain access to prior purchases. Apple perhaps gave us an interesting hint in that regard when they put administration of Family Sharing in the iCloud settings, not the iTunes & App Store settings.
