Same happened here in Belgium when Tumulus beer was sued by Coca-Cola because they have a fruit soda called Tumult.
The chance that the beer and soda will ever meet is infinitely small as the one is (very locally) distributed in Belgium and the other mainly in southern France, a distance of about 800 km at least.
After a couple of years an agreement was found. Tumulus beer still exists as such but may not use certain colours on its label and may not use 'numbers' as a name (the original claim was about a beer called Tumulus 800). So both parties pretended they won the case.
It did cost the local brewery about 20,000 Euro (22,000 USD) though, peanuts for Coca Cola but a huge loss for a local brewery.
"Blaming and fining the site because some people misuse it seems like setting a really dangerous precedent."
No it isn't. Today you posted an article where you find it imbecilic that a website killed all comments on its website because too many posters were insulting etc... Techdirt's simpler than life solution was that this website should monitor the comments before allowing them.
This is EXACTLY the same situation. TripAdvisor should monitor the comments. Point.
It happens everywhere. Sabam in Belgium routinely asked (and still asks) copyrights fees for amateur performers performing their own songs, threatening to close the gig down if they don't pay beforehand. Needless to say that these performers never see their money back...
In Orwell's A Clergymans’s Daughter Macbeth, Act V, scene VIII the 'womb' word is used, enough to make a parent write the following letter:
To my mind it’s a disgrace that schoolbooks can be printed with such words in them. I’m sure if any of us had ever known that Shakespeare was that kind of stuff, we’d have put our foot down at the start. It surprises me, I must say. Only the other morning I was reading a piece in my News Chronicle about Shakespeare being the father of English Literature; well, if that’s Literature, let’s have a bit LESS Literature, say I!
