Let me give my full 2 cents here:
Someone who asks about a certain licensing type, and follows Mr. X's advice. That someone gets sued. Who fault is that? Mr. X's advice? Remember, this is an advice. Someone who is doing business decisions with information found on the internet, it doesn't matter how reliable that information is. You should get legal advice from a specialized lawyer.
The idea is: if you ask about licensing issues on product Y, and assumes the responsibility of making a decision based on a internet based answer, you should take the responsibility. It's not the guy who answered fault. That's like blaming your friend when he advices you to break up with a girl.
If someone asks if it's legal to download and commercially use Google Earth's imagery, and someone answers yes, it's our responsibility to place different views on that matter. It is not OUR fault the decision the FINAL user will make.
As I said: 2 cents, or 3.
