I thought the whole point of these camera LEDs was to have them wired to/through the power to the camera, so they are always on when the camera is getting power, no matter what.

Having the LED control exposed through the firmware completely defeats this.

I can't find it now, but recently I read how one company's design team added this feature to their laptops. A subsequent review by the team responsible for manufacturing found that they could change the circuit to cut down on the part count to save money. The light was still there, but it was no longer hardwired. The company continued to advertise the camera light as being hardwired even though it wasn't.

That fact pattern would setup a solid fraud case against the company and necessitate a recall at a minimum.
