 In 2004, the Alexis de Tocqueville Institution (ADTI) announced its intent to publish a book, "", showing that the Linux kernel was based on code stolen from Unix, in essence using the argument that it was impossible to believe that Linus Torvalds could produce something as sophisticated as the Linux kernel.The book was never published, after it was widely criticised and ridiculed, including by people supposedly interviewed for the book.It emerged that some of the people were never interviewed, and that ADTI had not tried to contact Linus Torvalds, or ever put the allegations to him to allow a response.
