Copyleft discourages me from adopting the technology, I'm not much for including anything with a copyleft license in my stack. I clearly understand the need to make a profit and have nothing against it ... I understand that you feel that SaaS monitoring would be a problem and that this project is not just technology to support your primary product (the zerotier network stack), but that it is a product you wish can generate a profit on its own. Maybe the ideas behind CockroachDB's work could be helpful? https://www.cockroachlabs.com/blog/oss-relicensing-cockroach...
