The problem is the author defines "progress" in a very different way than RMS does. Is progress number of users or is progress getting the best possible system without sacrificing the core principles of Free Software? If you are going to throw around the word "traitor", then you are talking about principles. Nobody can say RMS has sacrificed his beliefs at any point. If you wanted to write a blog post that said "RMS is not the best spokesman/salesperson for free software", I'd believe that. But traitor and a bad seller are two totally different things.
