WORD PIRATES
Dan Gillmor and his sidekick David Weinberger have created a website to highlight words that "marketers, politicians and other short-sighted, self-interested, sticky-fingered people have been stealing... Not only do they take them for commercial purposes, but they misuse them entirely. They're Word Pirates and we're going to take back what's rightfully ours."

This is how our lowly heros at wordpirates.com intend to do it: "We can refuse to accept these translations into inhuman language. We can use the words to mean what they did before the pirates looted 'em. We can list and discuss pirated words here." Link

Don't the French have an offical agency for this kind of thing? We English speaking Americans have to rely on the power of persuasion in the free market.
