I bet the intellectual property creators don't find it charming. This is just P2P file sharing using dead tree technology. Because they maintain a physical presence the lawyers will have little trouble shutting down their "servers" and seizing their inventory.
If you want book content, you should support the creators and pay for it. We're not in China where all intellectual content creators go bankrupt. Some fringe P2P has its benefits, but content sharing shouldn't be so easy the average customer does it.
We have to have laws that support content creators. They need to make a living.
So, are you against tax supported public libraries too?
What about used book sales at St. Vincent de Paul and other charities?
