Let's see https://opensource.org/definition-annotated/, _the_ definition for open source, specifically the sections titled "No Discrimination Against Persons or Groups" and "No Discrimination Against Fields of Endeavor":
"The license must not discriminate against any person or group of persons."
"The license must not restrict anyone from making use of the program in a specific field of endeavor. For example, it may not restrict the program from being used in a business, or from being used for genetic research."
So what GP claimed seems to be exactly Open Source's point, no?
