For situations like this add "for $10k you get a commercial license". (Pick whatever price you think is right). Put that in your readme for visibility. If they are paying lawyers $500/hr to review licenses for peace of mind, they can afford $10k for commercial license. If they don't want to pay $10k then they are freeloaders and you're not loosing anything. This is something that sqlite does. See https://www.sqlite.org/prosupport.html https://www.sqlite.org/prosupport.html: "The SQLite source code is in the public domain, and is free for use by anyone and for any purpose. No license is required. However, some users desire a license so that they can have warranty of title, or just because their company lawyers say they need one. A perpetual license and warranty of title for the core SQLite source code is available for this purpose."
