I am another person who tends to agree that the term "free software" is needlessly vague. That is why I tend to say libre software.
However, the problem is that the word "libre" may not be known to some listeners, as it's a fairly unused word in everyday English. Therefore, I believe the simplest solution is simple: just say "freedom software". It is, after all, just the extension of free software. But unlike free software there is no ambiguity about cost, and unlike libre virtually every English listener would understand the meaning. (Even if they have never considered the issue of software freedom before) Another trivial benefit of just saying freedom software is that the FSF doesn't really need to change it's name, as the acronym works equally well. I understand that the term freedom software is unlikely to take off. And I know the free software movement (or freedom software movement, as it could easily become) has much more pressing concerns than a name change. Just an idea that I wanted to share.
