The primary species being hunted, pilot whales, according to the IUCN is least concern (the lowest rating) and they consider the hunts sustainable: https://www.iucnredlist.org/species/9250/50356171 The dolphin species aren’t endangered, either.

If you object to this on the basis that they’re intelligent that’s fine, but I also hope you don’t eat pork, since pigs are also highly intelligent (and for factory farmed, they lived and died in far worse conditions).
