I agree with unserializable that the NNUE is data
Doesn't matter: "This License will therefore apply, along with any applicable section 7 additional terms, to the whole
of the work
, and all its parts".
It is distributed as a part of a GPL program, therefore it is covered by GPL.
I already posted the link to how BusyBox litigated and get compensated for those type of violations.

Chessbase could try to distribute only the "improved" NNUE under a different license, but is not clear if that would be enforceable.
However, their main selling point is ease of use. They offer a complete package with a GUI, a strong engine and a small database all pre-configured and easy to install. It is certainly an added value for which many customers willingly pay.
What I find disconcerting is the abrasive personality of the people involved in those interviews and articles; the other time it generated resentment in the lc0 community and is now on the same path with the Stockfish' one.
It also seems bad marketing, they could simply advertise it as "an improved Stockfish, highly tested and with an optimized evaluation system tuned analyzing million of games..."
