Don't you know that you are criminals?
We are criminals with a high IQ so that we don't steal money no more but books.
I heard that the police has arrested a group of people hiding in a cellar and reading stolen books.
Sorry for these bad jokes...
I don't think that the community is made up of people who are pirates or guilty in stealing books. Unfortunately our reader device can not provide us yet legal content, but we have to live with it as it is. Not using it would be a bigger crime to the mankind.
As long as the desired book is not available for the particular ereader, you are using, you are not guilty, if you get it from somewhere else, because you have no other choice. I think the publishing industry is for us and not we are for them. They have to comply with our needs first, because we are the customers, I guess.
