Very true , most recently Apple went after Ethereum Classic and removed Shape Shift from the app store. Apple has historically had a somewhat mysterious methodology about how and why apps are included or pulled, but the crypto currency arena displays this best. If you look at the position Apple has taken towards crypto currency frome the begining. I am amazed that any Bitcoin or alt coin wallets are allowed in the app store at all. When you factor in Apple's fintech aspirations as a payment facilitator it becomes clearer that there may indeed be a method to the madness.
