Article author here, I admit this is fairly specifically targeted at the term "Open Source" as that's specifically the term I believe to see misapplied most often. I wanted to write an article that I could share to provide some context when raising issues regarding licensing. While I could have gone a lot deeper into also describing "free software" and the history of the terms, I wanted something rather direct that won't serve more confusion (Since often this could be the first introduction to the meanings of "Open Source" and "free software").

Maybe I could add a "Further Reading" section at the end though with links to such topics.
