مطلبی در سایت gnu.org تحت عنوان The Danger of E-Books منتشر شده که مقایسهای بین کتاب چاپی و کتاب الکترونیک از نظر سلب آزادی....
With printed books,
You can buy one with cash, anonymously.
Then you own it.
You are not required to sign a license that restricts your use of it.
The format is known, and no proprietary technology is needed to read the book.
You can give, lend or sell the book to another.
You can, physically, scan and copy the book, and it's sometimes lawful under copyright.
Nobody has the power to destroy your book.
Contrast that with Amazon e-books (fairly typical):
Amazon requires users to identify themselves to get an e-book.
In some countries, including the US, Amazon says the user cannot own the e-book.
Amazon requires the user to accept a restrictive license on use of the e-book.
The format is secret, and only proprietary user-restricting software can read it at all.
An ersatz “lending” is allowed for some books, for a limited time, but only by specifying by name another user of the same system. No giving or selling.
To copy the e-book is impossible due to Digital Restrictions Management in the player and prohibited by the license, which is more restrictive than copyright law.
Amazon can remotely delete the e-book using a back door. It used this back door in 2009 to delete thousands of copies of George Orwell's 1984.
