That's entirely the fault of the English language. The same term when translated into many other languages (including my first language) creates no such confusion - because they have different words for free as in free beer and free as in free speech.

The point here is that that linguistic peculiarity in just one language doesn't make the word 'free software' invalid or unsuitable, as long as 'free software' is a recognizable term (which it is). This is why FSF makes this explicitly clear with an entire article.
