Apple blocking SkyDrive from iOS store, wants cut of revenue
The first 7 GB of SkyDrive storage is free, but users can buy as much as 100 GB of storage.
Now Apple is insisting that Apple should get a cut of any SkyDrive purchases made via their devices, be it via the official SkyDrive app, or via integration with 3rd party apps.
That cut is 30%, and the policy is consistent with the same one which Dropbox suffered from, which in the end forced them to remove any way for an iOS user to purchase additional storage.
