Incidentally that article implies that Facebook contstantly tracks your geo location even when you do not expressly check in.
We are OK with Facebook doing this and exploiting the data for monetary and market advantages.

We use the same IP2Geo prediction algorithms that Google and other web companies use -- essentially determining city level location based on IP address.

If it's any comfort, most people have push notifications turned off for the main Facebook app (understandably since we send quite a few of notifications). However anecdotally some of the survivors of the attacks mentioned that they got phone calls from concerned friends / families while hiding in the Bataclan, which was understandably stressful.

We are not OK with the NSA doing this and (theoretically) not viewing the data. We are OK with Facebook doing this and exploiting the data for monetary and market advantages.
Hey everyone! FB engineer here who wrote the original code for this and gave the talk during @Scale 2015. There's a recording of our talk here: https://youtu.be/ptsCWGZW_P8?t=333 That's a bit more visual and easier to understand. At the end of the day its really just DFS with seen state and selective exploration :)

If you notice, the times people really get upset about companies tracking their personal information is if it's either not disclosed or it's done in a shady manner.
Also, capitalist societies tend to treat state actors differently than private corporations. It's much easier to choose a new corporation to interact with and the state tends to have a lot more personal/private data about you (which you're required to share with them).
Nitpicking here, but that does not follow. Starting from a random user and hopping 5 times in all directions you'd expect to explore about half of the graph.
