Some terms were defined by a community and their use defended.
Others were defined by a community, appropriated by others, distorted by others and subsequently abandoned by the original community.
And yet others, were abandoned and then reclaimed by the original community.
"Open Source" is in the first category, defined by OSI and defended by the FLOSS community. It is actively being defended, and fish much bigger than you have failed to topple the community.
Regardless of what other uses the word open has/had, "open source" was defined by OSI and they are authoritative over the term.
