The term "free software" was effectively coined by RMS & The Free Software Foundation. It is used explicitly when referring to copyleft licenses, which restrict certain uses of the licensed software in order to protect user freedoms. You can argue that other people use the term in other ways, but the most commonly accepted definition is the one used by the FSF.
The term "open source" is somewhat vague. Software that is merely "open source" is not necessarily licensed in a way that allows redistribution/modification. The only thing guaranteed about "open source" software is that you can read the source.

'Open Source' was/is a rebranding of the term 'Free Software' to make it easier to sell to suits. Eric Raymond has said as much about his invention of the phrase. The idea that it's just about "being able to read the source" is wrong. It's not vague at all, you just didn't do your research.
The only people looking to redefine (yes, redefine, there is no supposed ongoing dispute or vagueness about what it means to be FLOSS software) are those looking to push their own agenda, its not an honest conversation and never has been.
