This argument doesn't contradict the article.
An expensive iPhone ships with iOS and a rigid security model.
If you tap the `about` button 16 times and click a confirmation dialog, you disable certain security mechanisms against arbitrary software installation. Do something else easy but impossible to do accidentally, and you unlock the bootloader. You progressively lose portions of your warranty in doing so.
This is the path I think we should be going down.
Citation please? It’s my understanding that there is no officially approved way to unlock an iPhone.
They’ve had something like that for a long time on Android, and I think it’s a reasonable middle ground between making the platform open and closed. But as far as I know, Apple never did something like that on iOS.
