It's because very often, the scene in a movie/TV show/music video is designed to highlight and promote the product.
The art gets compromised so that you can watch an ad.
The worst one I've seen in a while was in Stranger Things season 3.
One group of characters got food from Burger King, then took out and named every item in their bag on screen and then, they had a 5 minute argument about what flavor of milkshake is better.
Another group of characters got into a long argument about new vs old Pepsi and they even compared the new one to John Carpenter's The Thing.
The show stopped in both of those instances in order to sell products. Suddenly, there was no plot, just a commercial.
