Guys, before rounding up a mob, please try to find out the story from the other side as well. To put it simply there was a complaint about Tfl killing an app last week or something, AFAIK that developer didn't get permission to use the data whether or not it was publicly available or whomever used that data. It states in Tfl's website that written permission is required for certain things and I wouldn't be surprised if they didn't get such permissions. In the article I noticed slight whining about other people doing the same thing which is (slightly)comparable to illegal downloading of films, countless people do it, but ultimately you have to seek permission from the content providers as you're utiliing their services.
