I have heard a position mentioned that a project is only "open source" if it uses an OSI approved license. I am wondering what this means relating to BSD-style licenses in particular. For example, is it the OSI's position that every BSD variant approved by the University of California other than the specific template listed on the web site is unapproved?
<br><br>Would OSI's position be that projects using unapproved variants on these licenses for historical reasons (PostgreSQL for example uses an old-style BSD license with the advertising clause dropped) are not open source?
