Here is my attempt to draw an analogy.

There is a large banner next to the highway that shows some weather information that if properly organized (lets say monthly almanac) you would find people to pay money for it. The banner owner does not make money this way - he ask you to go to his website and signup for an account. But you drive the highway (internet) every day, look at the banner, write down the weather updates, and then offer them on your website as a sale. The owner gets angry and sue you. The court decides you are free to drive by the highway and you free to put your eyeballs on their weather banner, especially given the banner is available to everyone (LinkedIn profiles are avail to view without needing an account) and you are free to use the information you obtained for free without interference with said banner in a form of a monthly almanac that you sell. At the end of the day, the banner owner does not own the weather information that someone else put in there (for example a weather meteorologist).

I think personally its a healthy decision. Otherwise it would be similar to prejudice of who should be allowed to enter and browse a street store that by law is available to everyone.
