That is when Eman started attracting the attention of some of my friends who asked me for a copy of Eman. Those friends never cared if Eman code is included with the binary or not.

But I DO. I hold some copyright and I DO care whether you preserve my authorship or not, I DO care whether you comply with the license or not. This is something that any one of more than a hundred Stockfish developers could say. The license is to protect the copyright holder, not the end user. And it's not even hard to follow, just show a bit of decency.

It's despicable that people knowingly violate the license by removing all signs of authorship. The Eman case has been even more blatant than Fat Fritz 2 or Houdini, but since it was distributed for free and has a small reach many gave it a pass. Now Eman's author forced to comply with the license chooses to cease distribution (the alternative being to release the source). Though I must say I'm happy that it was resolved in some way, I would have preferred the other solution, for the overall benefit of the chess community (however I doubt if the license will be respected in the distribution to "friends").

From how it went it's easy to see that it's one of the "I'm not doing shit until you force me. And if you force me it's you who's the bad actor, now I HAVE TO stop distributing my hobby project" situations. Many people seem unaware of any wrongdoing, and I think that's part of the issue - people allow this to happen because they either don't care, or do care but still prefer to take advantage of it. Some even defend it - https://cumnor-chess-server.com/phpbb/viewtopic.php?f=9&t=480.

Everyone who uses such engines is just as guilty as the people who distribute them. Either follow the license as required or don't use the software, it's as simple as that, and no amount of "hobby" or "good will" will offset that. If you don't respect the people who allowed you to produce your software no one should respect you.

I write this because it saddens me when people compare our pursuit for our rights to some kind of a holocaust of Stockfish clones.

It absolutely is a good development.

The GPL open source license is extremely generous. Anyone is free to take and use the code. But if they modify it and release it as a separate project they are required to make their changes public as well, so if they are good changes they can be added back into the main development.

This is fair and equitable, and it's how open source projects evolve and grow stronger. What absolutely shouldn't happen is people like Khalid Omar, Albert Silver, etc who take free available, open source projects, make minimal changes, and hide their contributions. It's the end point of software development. Nobody can take a look at Eman's source, see if the specific changes make the engine stronger or function more efficiently, and build off it because they don't ever release it.

Developers like Omar selfishly feel like they can always take but never give back. Their "hobby" projects wouldn't even be possible without Stockfish and Stockfish developers. And for what gain? Either they don't want to reveal how minimal their "changes" are to base Stockfish, or they want to selfishly hoard their own modifications so no one else can ever build off them and improve them. In both cases there's nothing really lost.

Yeah nothing lost because Eman leaves again and thanks to the experience file we can improve it
