In reply to Otto.

heh, Wikipedia seems to agree with you too ... https://en.wikipedia.org/wiki/Open-source_software

I used to work on SMF which referred to itself as open source, yet had a proprietary license. I knew people were confused by that, but I wasn't aware of there being any real debate over the use of "open source" in that context until now.

(SMF is no longer proprietary BTW)
