Projekt Stockfish, koji se distribuira pod GPLv3 licencom, tu\u017eio je tvrtku ChessBase, opozvav\u0161i joj GPL licencu za kori\u0161tenje svog koda. Stockfish je najja\u010di od \u0161ahovskih motora koji se koristi na \u0161ahovskim servisima lichess.org i chess.com. Tu\u017eba je podnijeta zbog uklju\u010divanja koda Stockfish u proprietarni proizvod bez otkrivanja izvornog koda izvedenog rada. <\/p>\n

Tvrtka ChessBase poznata je po svom \u0161ahovskom programu Fritz od 1990-ih. Godine 2019. objavila je motor Fat Fritz, temeljen na neuronskoj mre\u017ei otvorenog motora Leela Chess Zero, koji je izvorno nastao na radovima projekta AlphaZero, otvorenog od strane Googlea. To nije predstavljalo kr\u0161enje bilo kojeg zakonodavstva, iako su developeri Leela bili nezadovoljni \u0161to je ChessBase pozicionirala Fat Fritz kao samostalni razvoj, ne priznaju\u0107i doprinos timovima AlphaZero i LeelaZero. <\/p>\n

U 2020. godini, ChessBase je objavio proizvod Fat Fritz 2.0, temeljen na engineu Stockfish 12, koji koristi vlastitu arhitekturu neuronske mre\u017ee NNUE (U\u010dinkovito a\u017euriraju\u0107e neuronske mre\u017ee). Tim Stockfish je uz pomo\u0107 pravnika uspio posti\u0107i povla\u010denje iz trgovina DVD-om s programom Fat Fritz 2.0 u Njema\u010dkoj, no, nezadovoljni ishodom, proglasili su povla\u010denje licence GPL na Stockfish od ChessBase-a i pokrenuli tu\u017ebu na sudu. <\/p>\n

Nije ovo prvi put da se drama oko koda Stockfish odvija, koji komercijalni motori preuzimaju ignoriraju\u0107i GPL. Na primjer, ranije se dogodila neugodnost s curenjem izvornih kodova proprietarnog motora Houdini 6, koji su pokazali da se temelji na kodu Stockfish. Houdini 5 je sudjelovao u natjecanju TCEC-a i stigao do superfinala devete sezone, ali je na kraju izgubio od Stockfish-a. U 2017. godini, sljede\u0107a verzija Houdini 6 uspjela je pobijediti Komodo u superfinalu TCEC-a desete sezone. Izvorni kodovi, koji su procurili 2020. godine, razotkrili su ovu nepravednu prevaru koja kr\u0161i jedan od temelja FOSS-a - GPL. <\/p>\n

Podsje\u0107amo da GPL licenca predvi\u0111a mogu\u0107nost povla\u010denja licence od po\u010dinitelja i prekid svih prava licenciranog korisnika koja su mu dodijeljena ovom licencom. Prema pravilima razvijenim u GPLv3 o raskidu licence, ako su povrede otkrivene prvi put i ispravljene unutar 30 dana od obavje\u0161tenja, prava na licencu se vra\u0107aju i licenca se potpuno ne povla\u010di (ugovor ostaje neprekr\u0161en). Prava se tako\u0111er odmah vra\u0107aju ako se povrede isprave, ukoliko nositelj prava nije obavijestio o povredi unutar 60 dana. Ako su rokovi istekli, onda se povreda licence mo\u017ee tuma\u010diti kao kr\u0161enje ugovora za koje se na sudu mo\u017ee zahtijevati nov\u010dana naknada.
