Brake Fluid Leak problems of the 2007 Subaru Outback

Stepped on the brakes while on the highway and they went to the floor. Fortunately I was able to grab the emergency brake and Dodge into the next lane otherwise I would have slammed into the car in front of me, causing unknown damage/injury. I used the parking break and manual shifting option to limp it back to my house a few miles away. I walked around the vehicle and found a puddle of brake fluid dripping onto the ground at the passenger side rear wheel. Upon further inspection, I found a metal brake line was leaking fluid where it was clamped to the vehicle body. As I was looking for the part/information on it, I came across a known recall for this problem. I contacted Subaru and they stated that the recall had already been done on 8/8/2014. Part of the recall stated that if it wasn't leaking at the time, they were to spray it with an anti-corrosion of some sort and call it good. Apparently that's what happened to mine because the lines are very rusty and corroded. Now they want to charge thousands of dollars to have the repair completed. If this is a known safety issue and the results of failure are possibly crashing at high speeds when the brake line ruptures, how are they able to spray an anti-corrosion fluid over top of rust and wash their hands of such a potentially dangerous/fatal known problem? recall #wqk-47, 14v311000, and wqg-43.
