This is very sad. I would be glad if we can have site to expose those patent trolls. Browser plugin which automatically displays "Those are patent abusers, don't visit!" when you try to visit given url's would be even better. Maybe that would build some pressure to not use abusive claims.
Imo it's because you are just a bunch of prudes. It's just literature which by the way is widely sold worldwide by various bookstores.
Besides Amazon accepted the book for publishing, did publish it, allowed people to buy it and now is pulling it off without any compensation for clients/author.
Looks like abuse from their side to me.
