Kicksecure - Secure by Default Operating System needs a rewrite/removal.
It’s dishonest to claim Kicksecure (even when all the hardening work is complete) is as secure as mobile platforms. Those have decades of work gone into hardening the security model.
Security is not just a checklist of features. Kicksecure’s sandboxing/MAC/verified boot/etc. isn’t even near iPhone/Android and there are numerous security enhancements in phones such as modern exploit mitigations or widespread memory safe languages that are not achievable with Kicksecure.
The claim that most Android devices have locked bootloaders is also dubious. Unlocking the bootloader and even using custom keys is part of the reference implementation.
And again, GNU/FSF are not good sources.
