OK, I just read it and I'm confused because to me, this ex-trainer, Bridgette, didn't watch Blackfish at all...
Bridgette's goal would be to end animal entertainment and the breeding program and she claims the only goal of Blackfish and it's director is to "free the whales" and to win an Academy Award. I'm certain, having seen the documentary twice now, that the main goal of the film is to tell the plight of the whales being used for entertainment and profit, and the horrors of the fact that Tilly is really only being kept for their breeding program because they can't legally catch Orca in the wild anymore, and to end animal entertainment and breeding. I don't recall hearing that anyone believes we can just release these animals back to the wild (in Tilly's case; he's been captive for 30+ years now and most have never been wild having been born in captivity), but in fact the hope is to release them to open ocean PENS in the hopes that they'll live the most normal lives they have left - it's gotta be better than a swimming pool for profit.
I question Bridgette's motives; perhaps sour grapes over not having a key role in the film or getting credit? She didn't shed any light IMHO other than a gross misunderstanding from what I've taken from the film
