You're right! I disagree that the perfectly balanced system is OSX but overall I agree iPhones should have better "hack-ability". As I've posted elsewhere: I agree, Apple should make it easier to boot non-iOS iPhones. Even provide some tools to write custom OSes for the iPhone hardware. However, Apple should only provide that service to the registered adult owner of the device, in person at an Apple store after deliv…
Can you think of what a bad application can do to a user when side loading but is impossible to do when Apple reviews it, If I am a bad actor I can submit an app for review and activate an evil mode after the application is approved. Maybe we can stop pretending that the lock is in place to protect the users, most Android users do not root their devices or install random evil applications and then complain to Google…
With sideloading allowed, an application/appstore that is actually a trojan horse could request permissions once to "download X" where X is innocuous. Later the trojan auto-downloads other applications to your phone to mine bitcoin, run a bot net, etc. Basically selling your hardware, bandwidth and battery life to the highest bidder.
With sideloading, alternate APIs could be scraped together into a "new std lib". These APIs would just be some C/asm lib that is a part of any application and accesses hardware without any permission management. At that point every possible bad thing can happen. "Sandbox it!" sure... but that is what Apple is currently doing... its just also auditing source code to ensure no one is maliciously trying to break out of the sandbox. With enough time, people will break the sandbox or people will complain the sandbox is too limiting and not "true sideloading".
All this said, is Apple's auditing system a 100% guarantee? No. But at least I know once the bug/issue is found Apple will close the hole. Meanwhile, its in a company like FB or GOOG's best interest to force ever more tracking onto users, and they know people will continue to use their services regardless of the complaints (like what happens today).
You might argue, "this is where government should step in". I agree! The problem is that the government isn't doing a good enough job protecting users from digital abuse (arguably might make it worse with weaker encryption). So in the meanwhile, I'm happy that at least Apple currently is trying to protect users.
