Just watched a documentary about it. Being bullshited to if you ask me. Usual stuff about it being the fault of humans invading their space - all that nonsense. At the same time showing dolphins riding the bow waves of huge cargo ships and fuel tankers - as close as it is possible to get - for fun. Instinctively people are uneasy about this. The bad dangerous stuff - with sharks - all happens in the water. As long as you are out of the water, even in a little boat, your are safe. But with these Orcas - being out of the water in a 30 foot yacht you are not necessarily safe, which must be a bit unsettling !! I reckon someone will get killed one day, and it will be sold as the fault of humans for being there.
