I find the article and the subsequent comments from Jan and Sylvain to be very accurate. They have led me to remark that "do-it-yourself" describes my software interests better than "open source" or "free software" does.
I am mostly interested in software that works as I want it to. Consequently, I pretty much require that the software be freely licensed, that the source code be short, and that the software be developed by volunteers. The terms "free software" and "open source" describe only the first of these points; they may suggest DIY, as they originate from hacker groups, but they technically only describe particular legal mechanisms that happen to be useful in the context of DIY software. Furthermore, elegant software is often easy to reverse-engineer based on the documentation and interface, so the free licensing of the source code is not necessarily important. I imagine that "DIY" will lose meaning as companies market proprietary products (perhaps internet of things) as DIY, but, for the moment, I think "DIY" suggests that people are encouraged to learn, run, and modify the software to suit their own wishes.
