No. There's no check for Cydia or other Debian Package frontends that are there to void your warranty or stop you from downloading cracked apps (they very well could do this). They only patch the security vulnerabilities that are actually used to break out of the app sandbox and run arbitrary code, something that, as we can see with Epic's Fortnite app, could be RCE'd into an app without Apple knowing. These vulnerabilities can and have been used by actual malware in the past[0], so Apple fixing them in iOS is a legitimate security measure.

Right, but there’s no non-security-vulnerability way to jailbreak. If jailbreaking was as easy as `adb oem unlock`, no one would need to use any security issues to jailbreak.

They mostly prevent jail breaking because the same processes that jailbreak a phone can often be used to hack peoples phones because they’re security loopholes.

My Samsung A40 has a toggle called "OEM unlocking - Allow the bootloader to be unlocked". That's in the developer options. My previous phone from Sony had the same option. If Apple wanted they could do the same.

Security loopholes are a different thing.

They prevent jailbreaking by not providing a way to do it.

They additionally prevent jailbreaking by patching vulnerabilities.

Only one of these things is being called out.

You can get into all sorts of theoretical discussions about how if there was a way to do it, they'd be increasing their attack surface since now they have to make sure this path is locked properly when the user doesn't want it, but people act like the only way for jailbreaking to work is for Apple to stop patching 0 days, which is not the case.

Meh. If the file system weren’t encrypted I’d agree with you. Now that it is we should be allowed to replace the OS.

And that's also why Apple insists on calling your personal computer(PC) a Mac instead. Clearly they don't think it's your computer.

tHiS IS nOt a Pc BUt a mAc, you know? ;p
