Who decides what Wilber means?

Continuing from this post, who decides what Wilber means? Or Adi Da? Just themselves? LP's suggestion implies that we can take their stated meaning at face value, that they know well the full extent of their meaning, and that we do not. So we must be careful in interpreting what they say but they do not because they have privileged access we lack due to Supermind? This guy I know explored this question 10 years ago and it still stands the test of time. In Wilber's own words, the problem arises when a theory tries "to make its context the only context worth serious consideration" (p. 113).
