I can definitely see the use case as it is annoying having to choose between actively looking at participants of a meeting on screen or _appear_ to look at the participants by gazing into the camera and not actually looking at them.
I sometimes use an Elgato Prompter to better enable eye contact during meetings. The camera and lens is mounted behind the screen so looking at the screen is also looking at the participants. The downside is that the screen is tiny and you leaning forward to read, say, a document does not look that great on camera. So either you have to zoom it substantially or read it on another screen, thus looking away from the participants. In this case though, you are not looking at the participants and faking that eye contact in this case would be kind of weird.
