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.

Huh. Now you've got me thinking. Are snaps redeemable? Are they forkable?
If you have all the AppArmor patches and use a custom snap store, I believe so. There's some inefficiencies with flatpak that are currently ignored. For example, every flatpak app has its own bubblewrap processing running, though they are light on resource usage. However, inter process communication is really inefficient, there's a lot of context switching. You have the app talking to the dbus proxy and the proxy talks the real dbus (there might even be a step between the dbus proxy and real dbus).
Meanwhile, for snap, this security stuff is handled by AppArmor security profiles. There's no need for a dbus proxy.
