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.
