Other things I don't vilify that bypass author and publisher income:
Handing a book you love to a friend.
Used bookstores.
1) Hoarders. People who steal just to amass large amounts of 1s and 0s on hard drives. They consume .00001% of what they steal. They weren't going to pay for it anyway.
These are the pirates people fear the most, for no reason.
Please steal my books.
The other 30% is directed at the young and the poor, which if you give them their way now, they'll be loyal customers in the future.
