I don't know anything about these. But would opening up iPhone make it easier for authoritarian governments like China to install backdoors on your iPhone?
From a theoretical point of view, relying on security through obscurity is a bad thing. From a practical point of view, having obscured everything did not prevent people from finding many security vulnerabilities over the years.
Now, Apple devices are all manufactured in China so the relevant security services probably have access to all the schematics they need. Oh wait they don't need any shenanigans Apple is fully cooperating with chinese government and that's why they're so present on the chinese market, woops.
Slightly off-topic from the question, but if you're looking for authoritarian governments you don't need to look so far away from home, see also CoIntelPro/Snowden/etc (assuming you're from the USA). I agree authoritarianism and social control are a scale and we could do worse than Global North countries like France or USA, but we still have a pretty bad record of human rights overall and that should not be dismissed.
