Editing Differences between Diffen and Wikipedia (section)

=== Licensing ===
A fundamental difference between the two platforms is their approach to copyright. Content on Wikipedia is licensed under the Creative Commons Attribution-ShareAlike (CC BY-SA) license, which allows for the free reuse, modification, and distribution of its content, even for commercial purposes, provided the original source is attributed.

Diffen's content is protected by a traditional copyright, with its terms of use stating "All rights reserved." This means the content cannot be legally reused, copied, or distributed without explicit permission from the site's operators. This approach contrasts with the open-content model that defines Wikipedia and the broader Wikimedia movement.
