And that isn't even the original meaning either! "open source" in reference to software was itself a term stolen from the intelligence community.

"open" is simply a vague word that you are assigning more meaning to than it actually means.

The ambiguity of the word "Open" has a long history. Going back to at least late 1980s, when X Window "skin" OPEN LOOK (by AT&T - Sun consortium) had license issues and Open Source Foundation started work on OSF Motif.

Obligatory "Stallman was right" here.

Seriously, though. Without legal teeth and against marketing, "Open" never much stood a chance.
