Considering that the intelligence of sperm whales is unknown but possibly roughly equivalent to that of humans, so that objective outside observers might consider sperm whales to be persons, what your company is planning seems to be very close to being murder or kidnapping and enslavement.
So I strongly suggest that your story end with the persons responsible for that program being arrested.
The first indication that colossal squid existed was body fragments in the stomachs of sperm whales.
The species was first discovered in the form of two tentacles found in the stomach of a sperm whale in 1925.
Sperm whales are estimated to eat many thousands or millions of similar sized giant squid every day.
I think that there would be many practical difficulties keeping either colossal squid or sperm whales in captivity.
Marine biologists have often wondered precisely how sperm whales manage to feed themselves, and there are some strange theories about their methods, including having built in sonic death rays to disable their prey.
