One of the benefits of contributing to WordPress is that contributors license their code under the GPL rather than assign copyright to the WordPress Foundation or another entity.
This updates the copyright notices in each of the bundled themes to acknowledge contributors own a portion of the copyright. For themes with a significant contribution from Automattic, the copyright notice is updated from Automattic.com to the legal entity Automattic Inc.
