As a personal anecdote, while I’ve heard smart people say they were using “open source” way back when, I had personally never heard it used in any way before starting to used Linux and the BSDs in the late 90s, when OSI came along and people started discussing it in that context.

I can’t say others weren’t using it before then. I can say say that I first heard of Open Source after I’d heard of Free Software.

Yes, "Open Source" is newer than "Free Software". The phrases was deliberately coined, yes in the 1990s, to cover different (and mostly broader) ground... because there was a desire for a clear distinction between them. Which there still is.

Well, OSI didn’t coin “open source”. Factually, the term existed before OSI started using it. People have shared examples of isolated usage before then. However, they definitely brought it, and the modern definition, into common usage.

Like, if people had collectively used the term 23 times through 1996, then 837,000 times in 1997 or whenever OSI popularized it, I’m fully onboard with saying it’s their term.
