The middle ground is "source available", although that usually means source made available by the copyright holder under terms that don't meet the Open Source/Free Software definitions. I think just "leaked source" is the best terminology here.

Source Available is the worst of both, unless there's a way to reproducibly build the source and check the results against the shipped product. False sense of security and no legal ways to use the code.

Ah, found it: https://en.wikipedia.org/wiki/Source-available_software

I see, never heard of that term. Still wish there was a term that encompassed all software that has publically available source code. I thought "open source" was it. The literal meaning of the term aligns so beautifully with it.
