This is cool! I think the loc-based licensing is smart. Did you consider making the source available under the commercial license terms to support supply chain visibility?
I'm definitely not qualified to offer an informed opinion on a specific license, but there are a variety to choose from under the general heading of Source-available Licenses. There are definitely tradeoffs so it may not make sense for you, but it might open up some portion of the market that might not consider a black box.
