The whole thing except the fonts was put under a very liberal open-source licence 10 or 12 or so years ago. (By then it was owned by Bellcore or Lucent, not AT&T.) Before then there were severe restrictions; is your opinion that by time the severe restrictions were lifted, it was too late because Linux had already become entrenched?
