I never considered any of FB privacy curtailments to be 'clusterfucks' in the sense that they involved Buzz-level incompetence, bad planning, or lack of foresight.
To the contrary, I always felt FB knew exactly what it was doing, and was operating in a very calculated way. Three steps forward and (maybe) one step back.
Just like Google did with Buzz
That was such a clusterfuck that for most people Google is in the same bucket as Facebook when it comes to 'caring about user privacy'
