Freedom isn't one of the 7 virtues, nor is piracy part of any religion that I'm aware of. So I think this may be rather wishful thinking.
Here are the 7 virtues and 7 vices, so piracy would almost certainly be viewed as a vice (greed, injustice, wrath ... take your pick):
Virtues
Diligence
Temperance
Charity
Justice
Patience
Kindness
Chastity
Vices
Sloth
Gluttony
Greed
Injustice
Envy
Wrath
Lust
There's also some lore that pertains to this subject you might find useful in the Cardinal Miracle of the Second Age.
