Bungwe la Stockfish Project lidalengeza kuti lathana ndi mlandu wake ndi ChessBase, yomwe idayimbidwa mlandu wophwanya laisensi ya GPLv3 pophatikiza code yaulere ya Stockfish chess engine muzogulitsa zake Fat Fritz 2 ndi Houdini 6 osatsegula ntchito zotumphukira popanda kudziwitsa makasitomala za izo. Mgwirizanowu umapereka mwayi wochotsa chilolezo cha ChessBase's GPL pa code ya Stockfish komanso kupereka kwa kampaniyi mwayi wogawa mapulogalamu ake.
Monga gawo la mgwirizanowu, ChessBase isiya kugulitsa mapulogalamu a chess omwe amagwiritsa ntchito injini ya Stockfish ndipo idziwitsa makasitomala za izi pofalitsa zambiri patsamba lake. Makasitomala omwe alipo azitha kupitiliza kugwiritsa ntchito mapulogalamu omwe adagula kale, komanso azitha kutsitsa makope omwe adagula kale ngati ChessBase ipangitsa kuti kutsitsa kugwirizane ndi GPL. Chaka chimodzi pambuyo pa mgwirizanowu, okonza Stockfish adzasintha kuchotsedwa kwa GPL ndikupereka code yawo ku ChessBase, yomwe yazindikira ubwino ndi kuthekera kwa mapulogalamu aulere ndipo yadzipereka kusunga mfundo zake.
GPL imapereka mwayi wochotsa laisensi ya wophwanya malamulo ndikuthetsa maufulu onse operekedwa kwa yemwe ali ndi layisensiyo. Mogwirizana ndi malamulo oletsa chilolezo chokhazikitsidwa mu GPLv3, ngati zolakwa zidadziwika kwa nthawi yoyamba ndikuchotsedwa mkati mwa masiku 30 kuchokera tsiku lodziwitsidwa, ufulu wa chiphasocho umabwezeretsedwa ndipo chilolezocho sichimachotsedwa kwathunthu (mgwirizano umakhalabe) . Ufulu umabwezedwanso nthawi yomweyo pakachitika kuchotsedwa kwa zophwanya malamulo, ngati mwiniwakeyo sanadziwitse za kuphwanya mkati mwa masiku 60. Ngati nthawi zomalizira zatha, ndiye kuti kuphwanya chilolezo kungatanthauzidwe ngati kuphwanya mgwirizano, zomwe zilango zingapezeke ku khoti.
Pofuna kupewa kuphwanya mtsogolo, ChessBase idzakhala ndi wogwira ntchito wodzipereka yemwe ali ndi udindo woonetsetsa kuti GPL ikutsatiridwa. Kampaniyo ipanganso tsamba la webusayiti, foss.chessbase.com, komwe zidziwitso zazinthu zotseguka zidzasindikizidwa. Kuphatikiza apo, ChessBase idzatsegula ma neural network omwe aperekedwa kuti agwiritsidwe ntchito ndi Stockfish pansi pa GPL kapena chilolezo chogwirizana. Mgwirizanowu supereka chipukuta misozi kapena kuwononga ndalama, chifukwa gulu la Stockfish Project likuyimira gulu lopanda phindu lomwe likufuna kutsatira GPL ndi ufulu wake.
