Huh? This is a paper published in Nature, and it does cite Olof Kindgren and SERV in the references: https://www.nature.com/articles/s41586-025-08759-9#Bib1

The paper itself is behind a paywall so I can't see it, but it looks from the references like they provided proper attribution.

It's unfortunate that some of the articles around it don't mention that, but it seems like the main point of this is discussing the process for building the transistors, and then showing that can be used to build a complete CPU, not the CPU design itself which they just used an off-the-shelf open source one, which is designed to use a very small number of gates.

Thanks to the Archive.org link, we can see that indeed they link directly to the SERV github in reference 38:

    38. Kindgren, O. et al. SERV - The SErial RISC-V CPU. GitHub http:/github.com/olofk/serv (2020).
