Weirdly, at one point, your reply no longer seemed to contain the phrase "term of art." It's back now; I must have been mistaken about the initial change, since you'd have had to edit it well after the expiration period.
In any case, "open source" isn't a term of art. It did not originate with ESR or with anyone else in the software development field, so it means whatever anyone wants it to mean.
