> The “open source” label was created at a strategy session held on February 3rd, 1998 in Palo Alto, California, shortly after the announcement of the release of the Netscape source code. [..] The conferees also believed that it would be useful to have a single label that identified this approach and distinguished it from the philosophically- and politically-focused label "free software." Brainstorming for this new label eventually converged on the term "open source", originally suggested by Christine Peterson.
Wrong.

I see that Eric Raymond used the term on November 18th 1997. Wanna place a bet that I can't find an earlier use than that? Perhaps you shouldn't trust everything you read as definitive...Anything else I said still stands though - including that it's foolish to try and paint everyone with the same brush.
I have no idea who first put the words "open source" together, and neither do you. I think it's much more likely someone grabbed the term and added their own agenda to it after it was already popular. Regardless, assuming the original intention was as you claim, that doesn't mean everyone who uses that term now shares that view.
