No one is conflating piracy with raid boats, killing people and physically stealing items.
Ignoring the nuance is just ignorance and pedantic.
As a matter of fact, most people likely don't even associate piracy with pirates or boats. It's almost universally used to describe obtaining digital content for free.
I think this is the more nuances understanding of the conversation. Using a word associated with violence and theft to describe something like copyright infringement is just over-the-top and ridiculous.
As a participant in English, I’m pushing back against a pair of definitions that, I think, conflate two very different concepts in a way that is damaging to the conversation.
