CDNs are typically one way streets... all data all the time from the CDN into a region... I mean, Joe User doesn't send his photo stream to Apple via Akamai. With Apple in the ISP, they can, and get more consistent performance uploading and downloading. Apple can basically have every ISP that peers with them set up a 17.*.*.* route and bypass the mid levels peer exchanges and jump directly into Apple's Routing mesh.
Currently, there likely parts of Apple's 17.* network that are carved off and routed to akamai et al, Akamai owns the dns for 'akamaicontent.apple.com' and rewrites it to the correct IP location for the route 'nearest' your ISP. So when
I was leaning towards the AppleTV future when referencing now Apple has that direct peer relationship with cable companies for uploading data in near realtime. If AppleTV was to say, be able to tell your at the precise moment what was showing on Comcast channel 238 in Philadelphia, by talking to the Apple Cloud (a lot easier than trying to figure out who in Comcast serves that information and in what format), that's a good thing. Taking it a step forward, any Live TV that generated (local public access channel), could come through this backchannel, and be restreamed back (nearly) live through Apple's CDN to any AppleTV box.
But in the general case, Giving Apple a peer exchange link into your ISP distribution center offloads all the chatter between Apple Devices/apps and the Apple Data Centers. Given Apple's Size and presence on 20-30% of the endpoints, and in the future always chirping about some AppleID this, Facetim Video that, photo stream this, iTunes Radio That, having Apple 4 hops away (you, your City ISP POP, your main ISP, Apple CDN, Apple), will make Apple Ecosystem Users' lives better, and the ISP's other users lives better (because their hops onto the Mid Tiers and the Peer exchanges won't be crafted up with all this Apple Traffic.

They manage their own multi-tier CDN, including caching servers placed inside of ISPs
I won't say if they use Akamai as a back end farm (the data has to be somewhere), but they are managing all the peer relationships themselves, the bandwidth, the dynamic DNS, etc.
The issue with CDN's is that they see part of your traffic and you see part of your traffic. When you manage all the traffic you can respond to demand a lot better.
When I worked for a major eComm Site (Big Box Electronics store), Akamai was something we cursed, because it was black magic... it worked when it worked, but when customers complained about poor static performance... they shrugged their shoulders and said 'We'll look into it, but it appears everything is working fine.' That may have worked in 2008, but in 2014, when you have an apple iPad, an Apple TV, and you rent from iTunes, and a 100mbps link via fiber, if you see 'the spin,' it's Apple's Fault.
