The full article title doesn't fit HN's 80-char limit, so needs to be shortened. The submitted title was "Data-hungry, invasive app is a voter surveillance tool of extraordinary power", which would normally be fine, but popping Trump off the head of the list was probably too much of a change, so made the title above be a prefix of the original, instead of a suffix.

The subtitle is “Both presidential campaigns use apps to capture data—but Trump's scoops up your identity, your location, and even your phone's Bluetooth functions.”
