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.

I love Flatpaks and have embraced them totally on my desktop. They just make sense for sandboxing applications with Flatseal. Distro maintainers also ship software with bad defaults. I want to be able to easily control that.
Sandboxing is nice, but is not exclusive to Flatpak. I'm talking about the software distribution model.
So you trade distro packages which you can usually customize pretty well if you need to (e.g. modified Arch packages on the AUR) for Flatpaks where you have no chance at all to do that because the package build script isn't available? And the problem still isn't solved because now the people who can set bad defaults still exist, they're just different people.
Aside from all the things Flatpaks get right, a sandbox framework built right into the design is a major win and in my case, it's one of the big reasons I went with it.
You can also modify the build script for any flatpak's manifest and create packages with
flatpak-builder. May not be as easy as PKGBUILDs but it's certainly possible.The problem of bad software defaults is easily solved with Flatseal. My point is that, it takes a few clicks to deny permissions to Flatpak applications as opposed to sandboxing a traditional app yourself.
Writing sandbox profiles for apparmor or something similar is usually a complex elaborate affair. And even when you do finally manage to get a working profile, it still requires maintenance to keep the sandbox functional as the target software updates. You won't face any of these problems with Flatpak's bubblewrap.
