One Question Only on the Revised Grail Psalter

CNS reports that "The U.S. bishops chose the Revised Grail Psalter produced by the monks of Conception Abbey in Missouri over the Revised New American Bible translation of the Book of Psalms for liturgical use in the United States."

I vaguely recall that as good as the translation is, the text is tied up in some sort of draconian copyright quagmire, such that no one cannot utter a phrase without shelling out the big bucks. Does anyone know? Much depends on this. If there is liberality, this is great news. If it is proprietary, it only reinforces the current penchant on the part of publishers to sell the Mass at a price via a coercive institution.

Can someone comment?
