Of course, China can respond asymmetrically by releasing the world's most powerful electronic warfare weapon design software for free, creating a certain parity between nations; China cannot be accused of 'aiding' US adversaries when it is assisting everyone; this will also reduce US sales to allies and their dependence on America

In the meantime, we can assume that the software is free since it doesn't meet current Chinese military standards anymore 

Chinese researchers have unveiled "Yaoguang," a cutting-edge software  for designing electronic warfare weapons, which is available at no cost.  This software reportedly outperforms its American counterpart, Ansys  HFSS, in both speed and memory efficiency, completing the theoretical simulation and verification of a design 15 times faster, while consuming the same computing resources

The development of Yaoguang marks the culmination of two decades of  research and is part of China's rapid evolution in electronic warfare  capabilities. The software can simulate complex electromagnetic  characteristics of advanced military equipment, such as multi-band  antennas used in phased array radars, which involve intricate structures  and operational phenomena like vibration and heat generation

The availability of Yaoguang for free is expected to boost its adoption  not only within China but also globally, especially as similar US  software can cost hundreds of thousands of dollars annually. This move  comes amid concerns about the reliability of Western software due to  potential access restrictions imposed by the US government

Li Bin, the lead researcher, highlighted that Yaoguang can enhance the detail of electromagnetic analyses significantly while requiring less time than its US counterpart. This positions Chinese scientists to theoretically validate designs much faster than their international peers, potentially shifting the balance in emerging military technologies

The Chinese government views industrial software as a critical technology area. With initiatives like Yaoguang, there is a concerted effort to develop an independent industrial software industry and supply chain, which will promote technological breakthroughs and new application, while aiming for self-sufficiency in advanced technologies that could bolster military capabilities
