N.B: According to the Wikipedia article, the quotation by Mr. Brand refers to the price of information, and not to its liberty.
The definition of the word "free" in the English language is bifurcated. It means both "gratis" and "vrij" (in Dutch;) "gratis" and "libre" (in Spanish;) "gratis" and "liber" in Romanian.
This is not word-play; the English-language usage of the word "free" is ambiguous, and its problematic nature is relevant in this case.
