Put tape over it. The webcam light is a security feature that lets you know when an application is using your webcam. Bypassing this feature would allow someone to watch you via your webcam, with out you knowing. Or worse, you forgot to close a meeting/streaming session and didnt notice the light is on.
There is a lot of malware based on turning off webcam lights, but leaving the webcam on.
I will say it sounds like a terrible design if the webcam light is impacting the video quality.
I have trouble believing System76 tests their builds before selling them
Its one thing to say you support being FLOSS, its another thing actually do it
I'm seeing a lot of lip-service to FLOSS, but not a lot of practicing what they preach.
I've been talking to a lot of members of the FLOSS community and stories like yours are all too common. People buy expecting full user freedom, and end up finding out that information they need is gated behind the service desk.
They use excuses like "we are a small company" -- but I ask you, which takes more staff time and resources. Answering emails and service desk requests one at a time, or just having a parts list up?
