My company had the marketing department design a few abstract backgrounds with company colors / logos, which look fine on their own, but incredibly weird when there's a blurry and badly cut-out person with a window behind them. Basically it looks like there's a challenger approaching in Smash Bros. We only have to use them when talking to people outside the company, but most people just leave them on all the time.
Personally I'm not a fan of background removal/replacement unless it's done properly, but I do like blurring. I use a good webcam and I mounted a soldering light above my screen as a ringlight which works surprisingly well. Plus nvidia broadcast for noise filtering and background blurring, which makes the task easier for teams to blur it some more without cutting into me. Overall I think it looks fine. My home office looks too messy and unprofessional when in focus, but has nice colors when blurred heavily.
My boss often sits in his closet with lots of suits and shirts behind him, which confuses the filter enough to replace all his hair with the company background.
I think people should just decide for themselves what to do and just learn the basics of how to do lighting. Nothing fancy, just make sure the light comes from the front, not from the back, use a proper webcam (or maybe your phone, that might have a better camera+processing), see if you can do something about your background to make it presentable or easier to blur. Of course some people don't have the luxury of a separate room in their house for nothing but work and the money to turn it into a movie set. Maybe they are forced to work in their bedroom / kitchen / closet and don't want everyone to see how they live. I think in that case background replacement is the lesser evil.
