Is the debate being simulcast on all the major networks? I seem to remember seeing the Trump/Harris debate on ABC, CBS and NBC (just with different talking heads before and after).
If so, ABC should broadcast the debate with fact-checking overlays (Pop-up video style?) and advertise the shit out of the fact that they’ll be doing this.
The last two Dell laptops my work provided me with have little sliders that physically cover the camera. I use them all the time while working from home.
