Projekt Stockfish, ki se distribuira pod licenco GPLv3, je to\u017eil podjetje ChessBase in mu odvzel licenco GPL za uporabo svoje kode. Stockfish je najmo\u010dnej\u0161i \u0161ahovski motor, ki se uporablja na \u0161ahovskih storitvah lichess.org in chess.com. To\u017eba je bila vlo\u017eena zaradi vklju\u010ditve kode Stockfish v lastni\u0161ki produkt brez odprtja izvornih kod derivatnega dela. <\/p>\n

Podjetje ChessBase je znano po svojem \u0161ahovskem programu Fritz \u017ee od 90-ih let prej\u0161njega stoletja. Leta 2019 je izdala motor Fat Fritz, ki temelji na nevronski mre\u017ei odprtega motorja Leela Chess Zero, ki se je prvotno razvijal na osnovi projekta AlphaZero, ki ga je odprl Google. To ni bilo kr\u0161itev nobenega zakonodajnega akta, \u010deprav so bili razvijalci Leela nezadovoljni, ker je ChessBase pozicionirala Fat Fritz kot samostojno razvojno delo in ni priznala zaslug ekip AlphaZero in LeelaZero. <\/p>\n

V letu 2020 je podjetje ChessBase izdalo izdelek Fat Fritz 2.0, ki temelji na motorju Stockfish 12, ki ima svojo arhitekturo nevralne mre\u017ee NNUE (U\u010dinkovitno Posodobljive Nevralne Mre\u017ee). Ekipa Stockfish je s pomo\u010djo pravnikov uspela dose\u010di umik programa Fat Fritz 2.0 iz trgovin DVD v Nem\u010diji, vendar pa niso bili zadovoljni z rezultatom in so napovedali umik licence GPL za Stockfish pri ChessBase ter vlo\u017eili to\u017ebo na sodi\u0161\u010de. <\/p>\n

To ni prva sezona drame okoli kode Stockfish, ki jo komercialni motorji zlorabljajo, pri \u010demer ignorirajo GPL. Na primer, prej je pri\u0161lo do incidenta z uhajanjem izvornih kod proprietary motorja Houdini 6, iz katerih je postalo jasno, da temelji na kodi Stockfish. Houdini 5 je sodeloval na tekmovanju TCEC in se uvrstil v superfinale devete sezone, a je na koncu izgubil proti Stockfishu. Leta 2017 je naslednja razli\u010dica Houdini 6 uspela premagati Komodo v superfinalu TCEC desetega sezone. Izvorne kode, ki so uhitele leta 2020, so razkrile to ne\u010dastno prevaro, ki spodkopava enega od temeljnih kamnov FOSS - GPL. <\/p>\n

Spomnimo, da licenca GPL omogo\u010da preklic licence kr\u0161itelju in prenehanje vseh pravic licenciranca, ki mu jih daje ta licenca. V skladu s pravili o preklicu licence v GPLv3, \u010de so bile kr\u0161itve prvi\u010d ugotovljene in odpravljene v 30 dneh od obvestila, se pravice do licence obnovijo, licenca pa se v celoti ne prekli\u010de (pogodba ostane nekr\u0161ena). Pravice se takoj vrnejo tudi v primeru odprave kr\u0161itev, \u010de nosilec pravic ni obvestil o kr\u0161itvi v 60 dneh. \u010ce so roki potekli, se kr\u0161itev licence lahko tolma\u010di kot kr\u0161itev pogodbe, za katero je mogo\u010de od sodi\u0161\u010da zahtevati finan\u010dne od\u0161kodnine.
