@cyberspook "When I say free, I mean free as in freedom, not as in price." - wow that confusion was hard to clear up.
Meanwhile good luck explaining "open source" in one sentence.

>doesn't make it apparent that it's its own type of software rather than freeware or just a source code made publically available
Free software isn't a "type" of software - it's simply software that respects the users freedom.

It's clear that free software is different to freeware and source-available software, as the names are different.
I haven't come across anyone confusing free software with freeware or source-available software myself.

>I think the name was simply an oversight on Stallman's part
Free software has been the idea from the very start.
Sure it has become hugely popular to use free to mean "free of charge" relatively recently, but how is that an oversight on rms's part?

Libre software is an interchangeable name and it's excellent until it comes to non-English languages.
