TL;DW: all the point they say opposing the initiative are straight up lies. Some other parts of the statement deliberately pretend to misunderstand the initiative.
Or far more realistically, just make the server binaries available. You can’t force companies (or individuals for that matter) to open source their code.
The Stop Destroying Videogames initiative deliberately doesn’t care how they make the games work without continued support, as long as they do it. Releasing server binaries (or code) is one way, there are others.
