I'm not the person to whom you have replied but I'd say one could look at it from another perspective. I do not like the invasion of privacy from having others look into my home when I haven't invited them to do so. So, when I have a choice, I'll always remove or replace the background.

I'm on Zoom calls for work about 10 hours a week and custom backgrounds are very popular. Personally my office is a complete mess and putting a custom background on is much easier than cleaning.

For the same reason, I use a custom foreground where possible.

That's why the custom backgrounds is important. It normalises it. People can just think you're using one for fun.
