Some cameras still turn off the video mode, it has been patched out in some nikon and Canon models as it's just a firmware limitation stemming from the same tax reason.
This is usually some screen timeout.
Also make sure your digital SLR or whatever expensive camera you're using as a webcam doesn't have a 30m video limit, which some do. This is one of the most recommended pieces of advice on /r/videoediting (non-professional) for new streamers.

For most people, if you want better video quality for Zoom meetings or teaching Yoga online or similar, then a relatively recent smartphone camera + better lighting and microphone is more than sufficient.
