It's not modifying content and meaning, it's preserving content and meaning. When you're on FaceTime, the image you're seeing is not captured from where your eyes are presented on the screen, it's captured from somewhere above. This is a technical defect and it means that when the person you're talking with looks you in the eye, you don't see that. This is correcting that flaw and makes it so when the person you're talking with looks you in the eye on their end, you see that on your end too. This is more akin to doing a white balance adjustment, such that you see what the scene is expected to look like rather than the raw data captured by the camera, it's just correcting for camera location instead of exposure. Another way to think about it is this is a software fix for a hardware limitation. In an ideal world we'd fix the hardware limitation, remove the software fix, and your experience would be unchanged (or actually, even better, because of the lack of distortion on stuff crossing your eyes).
