Having read Red Notice, I strongly suspect the plot is much thicker than a simple copyright violation. The fact that NGINX now runs the majority of web traffic would be a clear signal to the Russian oligarchs that this NGINX is a valuable commodity to control and Sysoev needs to be moved aside. I'm guessing they don't have a deep understanding of BSD licensing terms, but they understand the value of controlling the contributors, and the log files.
