> OSI decided to appropriate the term "Open source" to refer to something slightly weaker than "Free Software" but much stronger than "you can look at the source code". They are not in their right to do that.
This is incorrect. Over 20 years ago people who would later be part of OSI _coined_, not co-opted, the term (within the scope of software). It was coined to mean _exactly the same thing_ as "Free Software"; the OSD was directly derived from the Debian Free Software Guidelines and there have only been two licenses, as I recall, that are OSI approved and the FSF have said are non-free.
You also confuse "OSI-approved license" with "GPL", because the OSI (and FSF) have approved permissive BSD and MIT and many other non-copyleft licenses. Here you go: https://opensource.org/licenses/alphabetical
