Here’s another article. It interestingly says that an orca had an upsetting event with a boat in the past and is now teaching the pod to protect itself from the danger.

The orcas are doing this on purpose, of course, we don’t know the origin or the motivation, but the defensive behaviour based on trauma as the origin of all this is gaining more strength for us every day.
It is likely, according to the researchers, that a female orca in the group suffered a collision with a boat or became entangled in illegal nets and, as a result, changed her behaviour, with the others mimicking her.
