I have been a long time user of, and a firm believer in, Open Source Software - in fact, from before the term “Open Source” was in general use. I have no idea how widely known the history of the term is, but it should be remembered that the adoption of the name “Open Source”, and the associated founding of the Open Source Initiative, was a calculated move to disassociate free software from its more political dimensions and make it more palatable to businesses (if you want to know more, I suggest reading - History of free and Open Source software).
