> Don't you think it's interesting that it's an option for Macs but not iPad Pros? They both use the same SoC.

Apple has always sold iPads as a closed walled garden and Macs as an open platform.

Apple designed the Apple Silicon Mac hardware to allow you to run an unsigned third party OS without a negative security impact when you run MacOS, because it is an open platform.

However we have definitely seen examples of other formerly open platforms facing new restrictions.

Android was sold to the public as an open platform that Google is actively closing with new restrictions to side loading apps

Windows was sold to the public as an open platform, but Microsoft is locking out users who refuse to use an online account to access their local computer.
