Digital privacy.
It was very recently revealed in unsealed court documents from I believe 2013 that the Facebook app pushed a certificate to mobile devices that funneled all of everyone's decrypted traffic through their servers. That means every webpage visited, every file sent and received, every word typed passed through and was stored on a computer at Facebook HQ. One engineer was quoted as saying that Zuckerberg had a particular interest in looking at people's Snapchats. It was also revealed that Facebook had a data exchange partnership with Netflix where Netflix had open ended access to user's private messages.
Now you don't have to be a Snapchat or Facebook user to see how wrong and downright creepy that is, but if you bring it up with the average person you can see their eyes immediately glaze over. It's hard to blame them, it feels like a hopeless situation and it's much more convenient to pretend it's not happening. People have been completely indoctrinated into abandoning their right to privacy. It's a real shame because if we were paid as individuals what our data is apparently worth I'm sure that perspective would quickly change.
