Is it supposed to have mass appeal? I thought it was for a small number of people who are such high-value targets that an adversary would be willing to burn a zero-day on compromising them.
Fair enough, but some of the protections in Lockdown Mode seem straightforward enough that I'm not sure why they aren't enabled by default. A couple of examples:
1. Device connections - To connect your iPhone or iPad to an accessory or another computer, the device needs to be unlocked.
2. Configuration profiles - Configuration profiles can’t be installed, and the device can’t be enrolled in Mobile Device Management or device supervision while in Lockdown Mode.
That is Apple's statement, but I'd be surprised if 50% of iOS/macOS users noticed any significant change with lockdown mode on. Unless you are using shared albums or answering unknown facetime calls, there isn't much impact. JIT, WebAssembly, etc. can be re-enabled per site.
