What's the problem?
Is it that people that aren't on Facebook are having their data slurped. If so, I can understand being annoyed but people that do use Facebook, what did you expect? You're using and have been using a service that is free but cost millions to run each year. Yes I'm aware they make more money than it costs to run now but still. If it's free, there is always going to be a catch.
I think this will just get blown over eventually. All the slightly tech people will possibly stop using it but everyone else will just ignore the storing and carry on.
