If you are referring to licenses that prohibit commercial use or prevent certain types of users from using the software, those licenses are not open source because they “discriminate against any person or group of persons” or “restrict anyone from making use of the program in a specific field of endeavor”.

For example, if a developer offers their software in a source-available “community” version that is restricted to non-commercial use and a proprietary “enterprise” version, neither the community version nor the enterprise version is open source. On the other hand, if a developer uses an open core licensing model by offering an open source “community” version and a proprietary “enterprise” version, the community version is open source while the enterprise version is not.
