Interesting thread at summitpost.org, lots of (pent up) emotion between the lines. Personally, I have no problem with climbers doing what climbers do and s*** does happen. But the courtesy of assisting the search effort by carrying a beacon of some sort (whether a local MLU or a global PLB) to tightly define the rescue/recovery area is a small request. A beacon may or may not save your life, but it could save the life of a rescuer. Just let everyone know that the rescue/recovery teams are available, but they don't do windows (search).
