Sad that Apple does not allow you to delete your account. Even Facebook does?
PS; if you think I am wrong post a direct link how to delete within Apple's domain. Trust me it does not exist.
Actually there’s some security reasons why. An iCloud id have muliple purposes in the Apple ecosystem. You can use it like an e-mail address or caller/messaging contact id. Now imagine if they will free up your username and later someone else will register it. Or worst, you used that e-mail address to register in some other services.
