charset=UTF-8; format=flowed Content-Transfer-Encoding: 8bit Delivered-To: submit@bugs.debian.org Package: licensecheck Version: 3.3.9-1 Severity: serious Tags: upstream X-Debbugs-Cc: mechtilde@debian.org Hello studying how licensecheck works I found this file t/exception/Cecill/tv_implementpoly.reference which is under the CeCILL-C with Sollya-4.1 exception The license CeCILL is not compliant with the DFSG because of § 13.2 Mandatory Choice of Venue (Article 13.2) The Clause: "Failing an amicable solution... disagreements or disputes shall be referred to the Paris Courts having jurisdiction..." DFSG Conflict: This is considered a "Choice of Venue" clause, which the debian-legal community almost universally rejects as non-free. By forcing any user or contributor—whether they live in New Zealand, Argentina, or Japan—to travel to Paris and navigate the French legal system to defend themselves, the license imposes an unreasonable, prohibitive burden. Debian considers this a restriction on the core freedoms to use, modify, and distribute the software (acting essentially as a fee or restriction, violating the spirit of DFSG #1: Free Redistribution). Discrimination Against Amateurs/Beginners (Preamble & Article 9.1) The Clause: The text states that the software's "use is reserved for developers and experienced professionals having in-depth computer knowledge." DFSG Conflict: This directly conflicts with DFSG #5: No Discrimination Against Persons or Groups. A free software license cannot say that a tool is only for experts, businesses, or researchers. If this text is interpreted legally as a usage restriction (rather than just a poorly-worded warranty disclaimer), it prevents students, amateurs, and beginners from exercising their right to use the software. The Obnoxious UI Advertising Requirement (Article 6.4) The Clause: The licensee must "ensure that use of the Software, its intellectual property notices and the fact that it is governed by the Agreement is indicated in a text that is easily accessible, specifically from the interface of any Derivative Software." DFSG Conflict: This clause acts as an overly aggressive "advertising clause." While preserving copyright notices in source files is required and DFSG-compliant, forcing developers to alter the user interface of any derivative software restricts how developers can build and design their own tools. This conflicts with DFSG #3: Derived Works, which requires that developers have the freedom to modify the software and create derivatives without arbitrary restrictions on how those derivatives must function or be displayed (for example, if you make a headless, command- line, or embedded derivative, surfacing text in an "interface" is practically impossible). Over-Restrictive Notice Preservation (Article 6.4) The Clause: The licensee undertakes "to reproduce said notices, in an identical manner, in the copies of the Software modified or not". DFSG Conflict: While DFSG #4 allows licenses to require the integrity of the author's source code and copyright notices, demanding that notices be preserved in an "identical manner" without allowing any format modifications can be a minor friction point for DFSG freeness. If a Debian packager needs to convert documentation formats or refactor code structures, absolute identical reproduction of notice blocks can create technical/legal hurdles.
