A better title would be:
Alcatel-Lucent makes the source code of 8th, 9th and 10th Editions of Unix public
Since the general usage of the word open source has implications about the a "free" license to use too.

*edited for clarity and a typo.
A much more detailed discussion of the origin of the term and its initial use appears here [2]. The latter link in particular is interesting reading, because it includes the political dimensions (especiall w.r.t O'Reilly's difficulties with the FSF).
