If this self provisioning profile can't use all APIs on the native OS and doesn't allow alternate OSes, it still allows plenty of room for Apple to keep doing anti-competitive, user-lockin, censorship and anti-consumer things. Apple has deleted dev accounts for pointing out pitfalls in App Store moderation, and removed an app to let you check if an iPhone was jailbroken. iMessage and iOS are equally capable of locking in users, one with network effects, and the other with the only apps that work with other Apple products. Unlocked bootloaders would allow more fair consumer choice.
