From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

They developed new system calls (pledge and unveil) which restrict they system calls and file access of programs (here's a good writeup by Andreas Kling after he added support in SerenityOS: https://awesomekling.github.io/pledge-and-unveil-in-SerenityOS/). As an example, the Firefox port for OpenBSD uses them to heavily restrict what random websites can do or get from your system.

Just one example since you've somehow yet to see any.
