Ich spreche kein Deutsch, kann aber Google Translate verwenden. Ich kann mich auch nicht entscheiden, ob ein offenes Geheimnis gleichbedeutend mit einer Offenlegung ist.
I don’t have a dog in this fight, but this is an explicit declaration, it seems to me, not a secret. What is secret?

You can see the various changes in the changelog, which seem to be in part support for better reporting in Fritz GUI? The author change credits lc0 and credits the FF author with the net, which seems correct.

Again, what is secret?

The GPL allows commercial use of code and, in fact allows renaming of a project as long as you keep copyright notices intact (legally required) and keep references to the old project (an important courtesy). Actually, not renaming your fork can cause confusion with the original project.

Of course the network weights are not covered by the GPL but by whatever license ChessBase applies to it.
I don't think this would fly under the GPL. You can't release GPL code that is not functional without some additional data file that is not GPL.

if the code functions with any Lc0 NN and they keep the downloads separate , it does not appear to me as being as black and white as you state.

In details say... Author : Rajlich... F17 --->Rybka 6??? in CPU mode?
F17 --->FF GPU Mode ?
Nah, Fritz 16 would be Rybka 6. Fritz 17 would be Rybka 7. Or Rybka 4.4, for that matter.

Can someone with a computer that can't run modern Stockfish (because their CPU doesn't have some instructions) and needs to run a general compile please check if they can install Fritz 17 x64 at all? With Fritz 16 this was impossible, you were forced to install the 32bit version.

I'd refuse to install a version that could well be weaker than Fritz 15 64bit just because they don't care about users without "modern computers", so if the 32bit version is forced in this version again, I'll pass.

since it seems confirmed in that page the Rjalich is the programmer I wonder what Graham's comment means. Maybe it's not Rybka but a new engine?
