Orca rams into yacht off Shetland in first such incident in northern waters

I'm rooting for team orca.

Ide play a video game based on this. You play as different types of whales and you fight off party yachts with different attack moves.

The age of men is over. The time of the orca has come.

Can anyone explain why this is becoming a trend? Is there some reason why different groups of orcas would be attacking vessels?
