It's perfectly possible to have open and secure firmware simultaneously. You could e.g. force a wipe of encryption keys when unlocking the firmware like chromebooks do. That way you can meddle with the firmware to your hearts content and not leak any personal data to the FBI when they nick your phone. Or how about nonsensical "features" like cryptographically checking if a replacement display is signed by apple? How does that do anything but prevent third party repair? I'm not being dismissive. I just want a damn phone where I'm allowed to replace parts without having to ask permission from the manufacturer first.
