Although I think Ankit Sharma's answer is the best answer, I think the episode's ambiguous ending goes a bit deeper where Billy Bauer's reaction is concerned.
IMO Billy Bauer is actually the most complicated character to figure out, because on one hand he did the right thing and talked/listened to Chris and fulfilled Chris' request to get his girlfriend's daughter's password, but on the other hand, Billy went right back to doing what he was doing before too, as if he wasn't really affected by whatever happened to Chris & Jaden!
However, what he was trying to do was detox from the technology and human contact all together! So there's a weird catch 22 in "addiction" vs "disconnection" in terms of empathy, which are all thematic to episode, because it was Chris being addicted to social media that led to the car crash and his fiance's death. And then his later girlfriend felt that she couldn't understand why her daughter committed suicide and thought that getting into her social media account (as she was not connected to it) would help bring her some closure or understanding about why she did it.
There's just that odd juxtaposition of Billy being out there alone in the desert in peace and tranquility, being disrupted to try and help somebody, which he could only do with the technology the world currently has, but yet it's followed by the madness of not knowing if in fact any action helped anyone?!
It was good episode to contemplate the conundrum of the nature of man/the human condition vs the nature of man with certain technology vs corporate enterprise! Is humanity just naturally on the whole unsympathetic or does technology make us more so?
