the only way to change the infrastructure is to gain control over it. hard to do when power is entirely held by Facebook. Regulation is one way to exercise control, but I'd rather see some kind of mass boycott / unionization among social network users to force Facebook to be more transparent and secure about user data (for what it's worth, I've tried to set something up here [1] and here [2]).

This isn't a response. We don't design roads so they're less convenient for murderers than for other people.
Facebook on the other hand have put themselves in a position where they make a profit my offering proprietary mediation (via content selection algorithms and censorship) on top of UGC, as an ad-revenue optimization engine. Once you're in the optimized-mediation business, you're faced with lots of choices, and many of them will pitch people's lives against your profits (not just ad-revenues, but how many people to hire, and where to invest them).
