which is what the Stockfish developers have now done. I.e. if Chessbase starts to comply now, it would be too late.
ChessBase could easily comply with any open source license by linking the full source code, including the method they used to generate NN weights (if they think the license applies here as well), in a footnote.
It would still be a scam, because their claims of superiority, originality ("almost from scratch"), and innovation (see the funny part about technology from Japan) are wrong, and purposely so.
PNaCl required almost no modifications to Stockfish (https://github.com/niklasf/stockfish.pexe), supports multithreading and is still the fastest.
WASM and asm.js require the same patches (https://github.com/niklasf/stockfish.js). Most notably WASM does not yet have multi-threading. In the original Stockfish one dedicated thread is listening for new commands. Instead now the main search thread (since it's the only thread) has to check for new commands from time to time, which costs a bit of performance.
