I, for one, hope that interviews with experiencers like Mr Strieber are always done with the respect we would like shown to ourselves if we were ever to make the decision to go public about our own anomalous personal experiences, even if our motives are questioned in some quarters.
He is a case-study within a field, but also a person.
It may be that no solution will be forthcoming which accounts for all aspects of his case. However, it is enough that the facts of his case are recorded, I would argue.
The fact that Mr Strieber has been able to draw some financial benefit from his experiences does not necessarily mean they are untrue.
That he seems to be part of the new age subculture, or is a fiction writer, or a businessman, or that he continues to interact with the meaning of his experience in public (etc.) are all worth noting, but may not be instrumental.
It is also worth noting his own ambiguity regarding his experiences; he is unclear what they might 'mean' and is apparently open to the possibility that they were a product of research done in the fringes of the defence establishment via family connections, leading from early-childhood entrainment to adult episodes involving clearly-human agents speaking code-words which have been linked to mind-control operations. (He may have tended to infer that his experiences are a mixture of such manipulations and genuine contact with the paranormal, but this is unproven, and could be regarded as an understandable attempt to integrate his experiences while transcending the role of victim into that of a forerunner during a time of change.)
If we assume, for a moment, that his entire case is the product of such clearly-terrestrial actions, we can still infer some possibilities, concerning who might want to make use of this type of person to produce certain possibilities in the popular culture-at-large. Rather than exclusively focus on the question of "Is his story true?" or "Does he believe what he says?" I suggest we ask "What has Strieber meant to the culture? What has his case made possible in the popular culture, and for whom? What has (possibly guided) popular reaction to his case meant in terms of the perceived legitimacy/significance of various paranormal topics?" etc.
