The president of the FSF (Free Software Foundation), the well-known Richard Stallman, has ruled on the Commons Clause license and cited it in error regarding the name (ill-named) because it can be misleading, as it is not a free license. Commons Clause is not considered free by the FSF because it does not respect the four freedoms required to be considered as such.
As you know Commons Clause is a new license (or a "clause" that can be applied on another license to modify it) that has emerged at the beginning of the year and is causing people to talk (but not positively, but because of the lack of interest in it). Now Richard Stallman has made it clear while answering some questions on the iTWire portal and the issue about this license has come up. In fact, iTWire contacted the company behind the license called Fossa.io to find out about the lack of interest from organizations that judge whether it is an open source license or not. Fossa.io did not respond the iTWire requests, the company declined to answer the questions. A new company that I have not heard much about and that seems to be run by a certain Kevin Wang. Well, and to refresh the memory of those who do not know, the four freedoms I am referring to are: power running a program for any purpose, studying how it works and modifying it, redistributing copies, and improving the program and publishing improvements.
And it seems that it is the impossibility that a software under Commons Clause can be sold or distribute for commercial purposes those that conflict with GNU to be considered as free. However, I do see an ethical and moral purpose for Commons Clause, as some experts have cited, and that is to prevent a company from getting rich by selling a product or service by using source code created altruistically by another person or community. That is, the developer does the work and others profit by using it… it is true that this is unethical and has been done with many open source projects… see Apple.
By the way, I clarify, because it can be confusing. Imagine that you have software under an Apache, BSD, or GPL license. If you apply Commons Clause on any of those licenses or any other open source license, what you are doing is respecting all the permissions of the original license but limiting the commercial use of the software.
