I think the issue in question is that these were areas that were originally not under the flight paths, but the flight paths were recently changed to put their homes under them.
So, perhaps they deserve some sympathy for the reduction in their quality of life and in the value of their homes?
La Jolla isn't really local to the airport, and all the airplane noise I ever heard there was from military planes related to MCAS Miramar.
But for starters, it's a big tall hill with books and crannies, and if planes started turning east sooner after takeoff, instead of flying over the ocean, parts of it might get some noise. I'd bet some homes get the sound magnified by the local topography.
