The article is from 2016, and quite a bit has changed since then - both in the ecosystem (many previously "open source" companies moving away from that model), and in the new licenses available to be used. I really like the Functional Source License (FSL) (the main license under the Fair Source brand), and we've adopted it at my company. It's not open source, and shouldn't be compared with that. But you do get a lot of the same advantages as you'd get from an open-source product, such as being able to inspect the source code to get an understanding of how the system works.
