If Chessbase modifies Crafty and sells the resulting program, it would seem that under the GPL they must provide the modified source free of charge. If they have turned Crafty into a native Chessbase engine, it would seem that they need to release the source to that, which would allow others to know how to make native Chessbase engines.
