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.

who’s paying the bills for Flathub?
There are currently six companies listed here, but, the important thing is that the flatpak client software can install things from places other than flathub (and the server-side software running flathub is free software).
The snapcraft server-side software is closed source, and even if someone reimplemented it they would also need to fork the snapd client software as the snapcraft URLs are hardcoded and not reconfigurable.
