I did a 3-day detour into CS ethics which was anchored in this facebook controversy. We listened to 2 episodes of The Daily podcast about the scandal and talked about it. It was intersting because students' "solution" was to make a "paid" version of facebook to fix the problem, but I feel like that means that only people who can afford to pay are allowed privacy and privacy feels like a right, not a "extra service for a fee". It was a GREAT discussion though!
Also, if you want to think more about this there is a #EthicalCS chat on Twitter occasionally that is worth checking out. I know people on there have pushed my thinking about how to approach ethics in CS. It is one of my ongoing goals to incorporate this more into the class and this Faceebook story is ripe for that.
ALSO, it is worth listening to the Senate hearing with Mark Zuckerberg... it emphasizes the need for a course like CSP! There were certainly some misconceptions about technology that were surfaced. We talked briefly about that a class too.
