@LynnC Haha, thank you! We're a nonprofit "umbrella" for projects building free and open source desktop systems. Our projects (like Mesa, Linux kernel graphics, X11, and Wayland) are key infrastructure for Linux, ChromeOS, and even Android phones!
You can read more about our organization at https://x.org/ and about free and open source software at https://en.wikipedia.org/wiki/Free_and_open-source_software
(By the way: Mastodon, Pleroma, etc are all free/open source software, too! So it's a natural fit for us.)
