Eman chooses to cease distribution to comply with GPLv3

[Sopel]

By the way, I also checked CorChess EXE. There is only I. Ivec as the author. However, new Stockfish patches are constantly being released. Is Ivec the sole author?

CorChess: http://chess.ultimaiq.net/stockfish.html

Indeed, CorChess seems to be violating the license too.

You're wrong.
From the link Eduard gave click "More about CoreChess..." at the bottom of the site, which leads to

http://chess.ultimaiq.net/corchess.html

First sentence there is

CorChess is a clone of Stockfish [source code] maintained for better performance on long time controls,
trying at least partially to fill the gap between regular tests and demands of correspondence players.

[source code] leads to

https://github.com/IIvec/Stockfish/tree/corchess

The distribution of the executable on the previously linked site does not follow the license. Also the changes made to the program violate the license. I have taken steps to enforce compliance.

Because you have to have two clicks for "compliance"?

Because it is not compliant.

Sopel has discovered a new toy. If all the clone authors ignore him, as they should, then no one will point out the Stockfish Project’s own sloppiness with complying with the copyright provisions of the GPLv3.

I hope it is becoming clear to those not in the know that the GPLv3 is a very restrictive license.
It certainly is not free, and while you can see the code you cannot take it.
(except of course if you open up your own code -which clearly Eman author does not want to do)

lesson to learn: Beware of open source

I have to disagree. If you are planning on distributing closed source software that incorporates GPL software, like Eman, then it doesn’t permit that use.

If, on the other hand, you are planning to sell a service or data that relies on GPL software, like RedHat or ChessBase, then it’s perfectly fine (though some here may consider that immoral).

Just because the stockfish fans are confused about the GPL doesn’t mean the rest of us have to be.

From the charter -

Once a member gains access to the message board, he may read all messages and post new or response messages with the proviso that these new or response messages:

1. Are, within reason, on the topic of computer chess
2. Are not abusive in nature
3. Do not contain personal and/or libelous attacks on others
4. Are not flagrant commercial exhortations
5. Are not of questionable legal status.

From the charter -

…

5. Are not of questionable legal status.

You are not confusing one meaning of “legal” for another, I hope.

So the Stockfish lawsuit against ChessBase is of questionable legal status, as it has not been decided, whereas suggesting a scheme to commit fraud is of questionable legals status as in “criminal.” I hope you understand the distinction.

The context of this thread is not Chessbase but authors that break the law and thus the charter, not making public the source code.
