> What the heck are you talking about? What types of apps do you think you can’t find alternatives for on the Mac?
It's not about finding alternatives. I did for a lot of mac's default. It's about replacing the default option. On Ubuntu, you can remove the default login screen and use KDE's panel alongside the i3 window manager. Because they're not tightly coupled together. Imagine if you could have replace the MacOs top bar, because it is a program that just answers to some IPC protocol? Or the window manager would expose windows and their placements so you could script a layout without the accessibility workaround.
> And why wouldn’t you want SIP by default?
I want it, which is why it's not disabled on my computers. But I'd like to set my own snapshot of what I meant to preserve instead of Apple's.

I don't but I'm always a real sudoer and I have the capability to do `su root` anytime.
As I've said, it's about expert mode, not something on by default, but that can be and the system has been built to support it.
