Some people feel the need to hide their shitty apartment. I've seen someone advised that the background on their webcam makes them "look poor", where the concern was that looking poor is a (perverse) impediment to getting paid work, but they can't exactly move, especially under lockdown. It may be better to use a calm artificial background in that case. See also people doing online-conference presentations and Youtube videos. I've seen quite a few of those are using virtual backgrounds. Perhaps for the same reason - thousands of people may see the video, and some people, having made the effort to put on a nice suit/makeup/etc, get a haircut, and look their best, don't want thousands of people to see what their not so nice home looks like behind it.
