My experience when I worked on upstream open source software was that distribution package makers would routinely introduce subtle bugs into programs via the act of packaging. In fact on the project I worked on we stopped supporting users who didn't use our own upstream packages because the number of bugs introduced by downstream packagers was just so huge.
I can't see any real benefits to the Linux approach and never could. It's one of the reasons I ended up moving to macOS. There's hardly any malware there too and yet app developers build packages themselves.
