You're linking to a 36 minute video titled "Black Hat USA 2025 | China's 5+ Year Campaign to Penetrate Perimeter Network Defenses." There's nothing in the description about "USA company bought an Indian OS to turn into it's SOHO router/firewall product."
Either you linked the wrong thing or you need a better source.
