In practice, copyleft can be expressed in ordinary language as follows: I, the copyright owner, choose to share my intellectual property with everyone, allowing them to make modifications, and use it as they see fit, provided they share their derivative work under the same terms as I. We must all emancipate our intellectual works from the restrictions of copyright, so that we might enjoy unencumbered cultural expression and computing experience. I thus call on everyone out there who is a writer, artist, programmer— anyone who has something to share with the rest of the world—to license their work under the appropriate copyleft license.
