But since [oO]pen [sS]ource has a broadly understood meaning that's different, we shouldn't deliberately use the same description for both ideas.

If you want to describe it as "source available", I'll happily go along with it. It's not open source, though. The source is visible, but it's not open to use. I mean, you can find the leaked Windows source code online, but it's not open source just because you can look at it.
