As far as I understand the psychology of a hacker:
1.) He/She is only interested in immediate monetary value. eg. Credit Card number, SSS, Government ID, Passport and etc that he can manipulate in relation to identity theft.
2.) He/She will probably sell information that he/she got to third party for a profit.
Now, Pirate Bay, Kick Ass Torrent, Iso Hunt and the like are torrent uploads for hacked pirated software DRM. Usually the seeder will spare hard disk space and monthly internet bandwidth to have the copyrighted materials circulated online. Meaning, he/she is exerting effort and resources and gains nothing in return.
If you analyse this flow, it will definitely root back to deliberate leak/distribution of copyrighted materials in the hope of gaining more materials and keep the community of pirates alive.
Therefore, no matter what reason one gives to Paizo, definitely it will go back to that person and Paizo ain't stupid. As the saying goes, a thief will never confess a crime even if evidence surrounds him/her. This is human nature.
I do hope this gives light to the community. Let us support the publishers and buy what they sell if we like their product. Believe me, some of them literally rely on this livelihood to support a family.
Have a heart.
