The current title is "Our lawsuit against ChessBase – Stockfish – open-source Chess Engine", which I found confusing. Is Stockfish being sued? Does it belong to ChessBase? I suggest sticking with the simpler title from the blog, "Our lawsuit against ChessBase".
Open source chess developers warn about a commercial engine based on Stockfish - https://news.ycombinator.com/item?id=26185139 - Feb 2021 (130 comments)
I thought there were others - maybe someone will find one?

I agree. Likely a quick checkmate in court.
Stockfish has an opportunity to make money here. No?
On the other hand, if ChessBase is found (and ruled) to have distributed software illegally, the company and its executives might have another problem. I don't know the specifics of German law, but I believe that distributing software (or any product) illegally is actually a criminal offense (no longer a civil dispute). That could (theoretically/eventually) lead to criminal prosecution and who knows .. jail time?

I'm not sure if it's settled law on whether or not you need to license to use code...
I don't think it quite works that way: the license is really just an agreement between the user and the rights holder that they will not sue for infringement. So use without license really means "you may expect to be sued". The outcome of that suit would determine whether or not you "need to license to use code". I'm guessing there have been many cases where the copyright owners for some code sued someone for using i…
That they can sue is a non statement, you can sue for anything, but I don't believe it is obviously (or even likely) copyright infringement...
From older blog post: "In particular, the license states that if one redistributes a program derived from our work, the corresponding modifications of our sources and all information needed to build that program must be made available. Only after explicitly informing Albert Silver (the author of the net in Fat Fritz 2) of a license violation have matching C++ sources, but not the net weights, been made available. Obv…
Should I be legally compelled to share the net weights of my trained NN?
If this goes to trial, I think this might be the cleanest and most straightforward test of the GPL in court we've had up to this point?

I'm definitely not a lawyer/expert on this, even less about Germany specifically, but isn't actual financial damage required for financial compensation? While Stockfish might have suffered damage from ChessBase's behavior, if it can't be clearly specified as monetary damage, I don't really see how they could make money from this. On the other hand, if ChessBase is found (and ruled) to have distributed software illega…
(n.b. National Chess Day is today)
FYI if anybody’s looking for a chessbase alternative I use a combination of SCID vs. PC, Caissabase, and Stockfish to roughly clone it. I’m sure chessbase has a lot more features but these alternatives are good enough for an amateur like me. https://sourceforge.net/projects/scidvspc/ http://caissabase.co.uk/
Build an opening repertoire from PGNs.
Drill that using spaced repetition (like Chessable)
Import all my games from Lichess and Chess.com
Tell me when I deviate from my repertoire in those games.
Do you know of a software or combo that can achieve that?
