> Some people have the perspective that if a license isn’t open source, it’s proprietary. I think it’s more nuanced than that and believe there are three more license types worth naming: non-commercial NDA, non-commercial public, and ethical. It’s very useful to remember the U.S. government definition of commercial software: it is software that “Has been sold, leased, or licensed to the general public” [1] This means that a “non-commercial license” is a bit of an oxymoron to a lot of people. Their definition of commercial includes all software with a license, and does not depend on whether the software costs money. (Perhaps not entirely unlike how FSF does not define “free software” based on whether it costs money.) [1] https://www.acquisition.gov/far/2.101 https://www.acquisition.gov/far/2.101
