Our lawsuit against ChessBase (stockfishchess.org)

Article summary

The Stockfish project has filed a lawsuit against ChessBase for violating the GNU General Public License (GPL) by concealing the true origin of key parts of their products, which are based on Stockfish. ChessBase has been selling modified versions of Stockfish without providing access to the corresponding sources, as required by the GPL. The Stockfish team has tried to resolve the issue out of court but was unable to do so. The lawsuit aims to enforce the consequences of the license termination and protect the rights of the Stockfish developers.

• The case may hinge on the question of whether the neural networks used in ChessBase's products are considered part of the covered work under the GPL.

• The lawsuit may also raise questions about the business model of companies that use open-source software without proper attribution or compliance.
