Free, i'd be interested as well to hear PW's response to this one.
I haven't read those books, because i had the impression (from blurbs etc.) that they miss the point, along the lines u had mentioned.
I don't know about the american situation (PW does), but in my case in Israel there is pressure on me to write the story, BUT as fiction. A survivor who reached the stage of being able to publish a best selling novel is posed with a dilema. I don't think that a reliable testimony book is an option, it would not sell, and I don't believe it will make it to the shelves, if there are names there and all. (not screen, but real).
Writing a reliable yet selling account is a tricky one. ITs like either u paint it yellow (with celebs and sex) or science fictionize it (aliens ? etc.), or reduce the depth and create a detective-espionage drama. I can't think of another way, but would be happy to hear.PW's approach, to use the artistic tool is also valid, but again it uses art as a social means to avoid consequences. Artists have some license (although given Lombradi and others, this license is also limited, preferably one should go for the unstable artist nieche).
If I had financial backup I'd write an account, without the emblishments and probably with legal advice - I'd use some intials for names, to avoid defamantion law suits etc.
If u examine the "holocaust account" genre u can find some of the problems there as well, although the question of relibaility is already out of the way. Some writers, at least in Israel were accused of "yellowing" up their accounts, to gain audience. I think only Primo Levy managed to escape the pitfalls and still be a best seller. And he wasn't very happy...namely, his soberness was eventually his downfall as well.
I don't see any problem, on an individual level, if a survivor uses the experience in away that empowers her, with all the "Schticks" of PR and marketting (sex celebs etc.). However, it has damaged the perception of the problem in "serious" circles. BUt again, those circles really have betrayed their calling anyway, the intellectuals, the social activists and critics have persistently turned a blind eye to this problem, although there is ample documentation. PW mentioned in another thread, the problem of the "american progressive" left movement being raided and neutralized by MK slaves, thats a result of a stratetic decision by prominent leaders of those movements not to address this problem. So there is a situation of "betrayal of intellectuals and cultural elite circles" who are also the ones that control the bon ton in the publishing world. They are not there for this social issue, and therefore it leaves only the "yellow tacky" publishing arena...etc.
