Sorry, I stand corrected quoting from the OSD: "Open source doesn’t just mean access to the source code".
It's like me starting the cheese initiative and trying to control what others call cheese, a job that's typically reserved for governments.
I also don't care if somebody in 1975 said "I like to be open, and I'll let anyone look at the source." Old McDonald had a farm before McDonald's was a restaurant, but that doesn't mean that if you open a restaurant called McDonald's that is decorated like a McDonald's, you're not a scammer. I know your plastic fruit is carbon-based, but if you label it as "organic" you're a thief.
If you're not trying to scam people, be creative and make up your own catchphrase for letting people look at your source code - or don't even, because the whole idea of having a branding for allowing people access (and rights to) the source is imitation of the FSF and OSI.
Open Source isn't a brand, it isn't a trademark, it was hijacked by OSI to enforce their specific interpretation of a phrase that was already in use. OSI wasn't founded until 1998, over a decade after the term open source software became popular and was used throughout the unix and linux communities and in businesses such as Caldera. Before OSI came up with the OSD many creators of open source software had non-compete clauses in the licence.
Like I said above, they're as official as the cheese initiative I just made up.
No government has endorsed them, and open source is not a protected name in any country I am aware of.
They're just some arrogant American organisation that expects the entire world to bend to their whim, as usual.
They have successfully convinced a generation of developers that “Open Source” is pure and holy, but a licensee that includes a term that says something like no company making more than $100 million per year can use this software for free is unclean and maybe even evil.
They don’t want alternative licenses to exist because it hurts their bottom line.
