The CCA scoffed at the notion, claiming that the source code has a mere practical function and no expressive content.
The court saw it differently:
"Like the CSS decryption software, DeCSS is a writing composed of computer source code which describes an alternative method of decrypting CSS-encrypted DVDs. Regardless of who authored the program, DeCSS is a written expression of the author's ideas and information about decryption of DVDs without CSS. If the source code were compiled to create object code, we would agree that the resulting composition of zeroes and ones would not convey ideas.
