I use it both ways. As a software engineer I use it for various packages, which don't even need a releases page. But also as an end-user of open source software, I use it to download pre-built binaries of said software. Idk if you know, but there's a lot of open-source software out there. And github is the most popular platform for hosting it. And when I say software, I mean the kind where you don't expect your users to know how to build it from code themselves.
