wicked child, I'm afraid I can't agree with what you've said.
I'm a sufferer/trauma survivor and the book "Waking the Tiger" helped me greatly. It's about somatic experiencing, which Peter Levine developed. I couldn't find a somatic experiencing practitioner where I am, but I found a craniosacral therapist (with experience of trauma other than birth trauma) and that's very similar. It has been a key part of recovery for me.
I could not have got the same result from Vipassana meditation, and this kind of meditation would have been extremely dangerous for me. I'm not exaggerating. There are all sorts of psychological and psychical effects of trauma, and any kind of meditation was something I had to be very, very careful about. Especially anything about tuning into body feelings/senses, because my body was holding some feelings and senses that were beyong bearing - it was not a good idea to try to naively tune into that. I had some very bad experiences before I realised that. But even leaving that aside, it's absolutely not the same thing as somatic experiencing or craniosacral therapy.
I'm sorry, but I think Vipassana meditation as a self help for trauma survivors is inappropriate and risky. I'm not commenting on Ben Fry. I know nothing about him.
I really recommend the book "Waking the Tiger" to any sufferer, and imagine it would help supporters understand as well. Peter Levine has written a more recent book which I understand is more up to date with his understanding of trauma work. I haven't read it so can't comment on it, but it's called "In an Unspoken Voice: How the Body Releases Trauma and Restores Goodness".
