I don't even need GNU-freedom, regular MacOS is fine. I just can't live with a iPadOS anymore.
edit: you can pry locked down iOS from my cold dead hands. Love it exactly because it's a walled garden.
Start with a laptop, you believe they should be open.
Remove the keyboard so it's only a screen, you believe they should be opened.
Shrink that screen down, and now they should be locked down?
Why do the same restrictions bother them on a bigger screen is what I'm getting at.
What if the iPhone supported more traditional desktop resolutions when plugged into a display, you'd be staring at a screen with an Apple UI and more desktop/tablet like amounts of screen real estate. What of the walled garden then.
I would love plug-in display type functionality for my phone, but not at the expense of leaving the walled garden.
On the other hand, an ultra locked down macbook would sound pretty ideal for day-to-day browsing, handling financial tasks, work communications and so on. Really everything except the software development tasks I work on.
On the other hand, I do almost everything over SSH already. I guess I really could easily live with a completely locked down base MacOS install without any issues. Even Terminal.app isn't too bad anymore.
