Apple is resuming the controversial practice of having human employees review users’ commands to iOS on-board digital assistant Siri, the tech company revealed in a new software update on Monday.

Apple had previously generated controversy over the summer when it revealed that human technicians had been reviewing a small percentage of Siri commands in order to “grade” them and improve the software’s performance.

After receiving significant pushback, Apple halted the program and said it would release a software update that would allow users to opt out of the “grading” system rather than be automatically included. Monday’s update, iOS 13.2, gives users that feature.
