I have absolutely no idea what you're talking about. You're either misunderstanding something or something really needs to be changed in the docs.

Citing an article [0], a post[1] on the site states, "Security researchers over the years have discovered ways to detect what you are typing on the screen simply by looking at variations in the accelerometer." (Infomercial-esque strikethrough not retained here.)

Purism's solution, apparently, is hardware switches. As I understand it, the accelerometer isn't disabled via hardware switches unless all hardware switches are disabled, as there is no discrete accelerometer switch: "To trigger Lockdown Mode, just switch all three kill switches off. When in Lockdown Mode, in addition to powering off the cameras, microphone, WiFi, Bluetooth and cellular baseband we also cut power to GNSS, IMU, and ambient light and proximity sensors."[1]
