We are far from powerless. Facebook - the only valuable thing there are the contacts - they can be rebuild.
A new search engines can arise (we are long overdue anyway, time to reinvent the search is nigh - google has been giving crappier and crappier results for the past few years and is still the best out there)
There are a lot of devices that are still controlled by their owners. I have a lot of non technical people asking about encryption and migration to linux lately (pre scandals).
A lot of people have real IPs that allow them to receive incoming connections and are not forced to ask for port forwarding and nat.
There is always ways to create distributed p2p encrypted global network. And with opencompute there will always be enough free home hardware to back it up.
