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.

And you also need to trust your OS not taking screenshots of your apps or recording the text displayed onto your screen
There's plenty of links in this chain, there's a lot you need to be aware of if you're going to those lengths. Pick your battles
My os does not do that
I don't consider "wanting a secure app to be installed through first party means" to be particularly unusual. I know in Linux it's standard to just install random stuff from the internet with root. I've obviously done that myself, but for secure stuff I want first party. Making a flatpak wouldn't be hard (they probably just need to review someone else's work -- it's like an intern project)
So I went and looked it up, and signal-desktop is listed as a reproducible build, so theoretically you should be able to go and check that it conforms to the source

But this isn't anything I've looked into myself, so feel free to look into it
