Free as in beer and as in speech

An interesting thing this time on TV: a commercial of a mobile company where they say that after the freedom of speaking won from Ceausescu we will now get the right of free
speaking on the mobile (as in no money). I think this is something everybody could understand as a description of open-source with the free as in beer (the commercial) and free as in speech (won after the revolution).

Although the commercial is quite bad-taste especially after so many years after the revolution, it's an amazingly good description of the core free software movement ideea.
