I suppose I might have listed "form a company to commercialize" as one of the approaches, and tagged it as the one with greatest flexibility to add more offerings on top of license rights. I think License Zero, Tidelift, and other "sustainability as a service" offerings exist largely because the overhead of company-based commercialization is so high, and it doesn't scale well down to very small open source projects.
