Worth keeping in mind that the steam deck uses a distro based on arch, so it might be inflating the arch numbers in that steam survey.

Then by that logic, redhat is leeching off the work of the Linux kernel developers and the other Foss software in redhat

You can change the config so you don’t need to give the password every time.

Adding the persist option only requires it once every few minutes within a terminal session.

You can use the magic bytes to detect it. Pretty sure windows executables have MZ as their magic bytes

2 scenarios where it can be exploited:

Acquiring the ability to compromise a server or perform an adversary-in-the-middle impersonation of it to target a device that’s already configured to boot using HTTP

Already having physical access to a device or gaining administrative control by exploiting a separate vulnerability.

It’s a real-time operating system frequently used for small and embedded devices.

I’d just like to interject for a moment. What you’re refering to as Linux, is in fact, GNU/Linux, or as I’ve recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.

Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called Linux, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project.

There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called Linux distributions are really distributions of GNU/Linux!
