Apple's apps bypass firewalls like LittleSnitch and LuLu on macOS Big Sur

Both major consumer OS vendors seem hell-bent on bringing the OS layer under their complete control. As a power user, it's very frustrating. Meanwhile "desktop" Linux still kind of sucks, just like it did 10 years ago. I don't have much hope of seeing a compelling, unified UX out of Linux in my lifetime.

Curious, what sort of things make desktop Linux suck in your opinion? I’ve been on Linux for years as my primary machine and haven’t encountered anything that made me switch back.

Can you select a file in the whatever is the Linux desktop equivalent of Finder and hit the spacebar to get a quick look at the file native to the OS?

Can I run the software I need to be able to make a living?

Can I run multiple HiDPI displays that I can connect/disconnect as needed without causing issues?

I honestly don't know if these are or are not available features. The first question is a muscle memory thing for me and makes me thing Windows Explorer is broken. I know the second question is not possible, so after that it's full stop. Question 3 is something I anecdotally know that has been an issue in the past, but would be problem for me if it is not possible.

Yes, I use pcmanfm on Linux and the spacebar will open the file in the default program.

Depends on what you do. If it's mostly design work and you require Adobe products then Linux is not a good choice. For software development then Linux is great.

I never encountered problems connecting external monitors but also haven't tried connecting to an Apple monitor and makes me think drivers are probably non-existing for that.

That's not what QuickLook does. It allows the user to get a "quick look" at a file without launching a default application. Also, in macOS you get access to QuickLook from inside any application's Open dialog. That's a huge time saver when you have similar files and just need to see which one before doing a full open. Think large image files that you want to place in a layout.
