The point of using the GNU Affero General Public License (Version 3) is that it allows "users who interact with the licensed software over a network to receive the source for that program" (FSF).
Section 13 of the AGPLv3.0 contains:
[…] if you modify the Program, your modified version must prominently offer all users interacting with it remotely through a computer network (if your version supports such interaction) an opportunity to receive the Corresponding Source of your version […]
It says "if you modify". Does this really mean that the source only has to be made available if it was modified (assuming that I don’t offer/distribute the application itself, i.e., its binary, at all)? Or am I missing something, maybe somewhere else in the license?
In other words:
- I install a Web application licensed under the AGPLv3.0 on my server.
- I don’t modify this application at all.
- I allow people to use it over the Web.
Do I have to offer the source code of this application?
