A similar and related discussion is whether to talk about free software or
open source. Many people use the two as synonyms but that's not accurate. If
one knows his software history, he will know that open source was but a
marketing campaign for free software, started by Eric Raymond and Bruce
Perens. In a few years Perens realized the campaign was not a great idea and
left it behind and returned to the original terminology.
The difference between free software vs. open source is the same as with
GNU/Linux vs. Linux, the former spreads knowledge about and emphasizes
freedom. Which is kinda the point.
