Fat Fritz 2 is a rip-off

Or just fix the claim and Silver will arrange source code to be publicly available to meet requirements of the licence.
Great work once again Lichess! This reminds me of the fun time we had completely wrecking the Regium "self-playing board" scam. It's amazing how much effort this community can put into debunking such claims as these.
I agree with both the supporting side and the opposing side; the side that supports Fat Fritz 2.0 (ie Sarg0n) and the side that opposes FF2 (ie the 100 people that thumbs down Sarg0n's comments).

On one hand, buying FF2 basically means you're installing a more customer-ready version of Stockfish 12, which is somewhat nice in a way. On the other hand, the people responsible for developing/promoting FF2 are purposely trying to mislead people by pretending it is not simply just Stock-fish 12 (plus FF2 is encrypted as closed source).

To my understanding, the legality of FF and FF2 is kind of like a dark grey area. It looks like it's somewhere bordering between barely legal and barely illegal (mainly because it is not so clear which one it is, and will be up to legal interpreters to decide, just like many famous court cases). PERSONALLY I think it is illegal, but just because I think it is does not mean that it is. The law goes as following - If you use an open source app/program and then encrypt+sell it as closed source, that violates the open source license, even if it makes the program better.

In short, what I am saying is that I think it is nice to have a more customer-ready version of Stockfish (although in this case not so much due to the high price), but I also think what they did was basically illegal.
DrEykplaner - 'having a more customer ready engine statement' is also misleading. It takes less than a minute after downloading SF12 to add it to the ChessBase software. And when SF12 gets upgraded you just repeat the process and you have always the latest engine.
