Topping tech headlines over the weekend was news that the Justice Department is collecting data about U.S. citizens’ cell phones via airplanes.

The U.S. Marshal Service allegedly operates a number of Cessna aircraft, equipped with machines that mimic cell towers, which scoop up data from tens of thousands of unsuspecting mobile users. Though aimed at picking out fugitives and drug dealers, the program must collect data in bulk—sweeping up information about non-suspects—before weeding out the desired details. Non-suspect data is later deleted.

Meanwhile, Facebook will soon begin limited Pages’ promotional posts. Beginning in January, users will see fewer products and more friendly faces in their news feeds. This move, the social network acknowledged, will mean a significant drop in some Pages’ organic distribution over time. The majority however, will remain unaffected.

In other news, the FCC is looking for answers regarding AT&T’s plan to “pause” its gigabit Internet rollout. The carrier last week blamed the ongoing net neutrality debate, saying there is too much uncertainty to invest in the costly rollout of the U-verse with Gigapower service. But the FCC wants a better explanation, including data on current and possible future fiber numbers.
