Sections 3.1 and 3.2 of the CeCILL, edited and with emphasis added:
3.1 The Licensee shall be deemed as having accepted the terms and conditions of this Agreement upon the occurrence of the first of the following events:
- (i) loading the Software by any or all means, notably, by downloading from a remote server, or by loading from a physical medium
3.2 One copy of the Agreement...has been provided to the Licensee prior to its acceptance as set forth in Article 3.1 hereinabove, and the Licensee hereby acknowledges that it has read and understood it.
If a distributor, be it the Licensor or a Licensee, simply offers a download link to CeCILL-licensed software without first directing the user to the license, have they done anything wrong?
