It might not always be Zoom's fault. I know when I use a vTuber overlay (I'm not a vTuber, was just curious how it worked), it interfaces directly with the camera input/output, not later programs which use that camera information. In such a situation, no amount of "idiot-proofing" on Zoom's part would prevent me from appearing (or not appearing as it may be) on camera in a certain aesthetic.
