I'm 90% sure Amazon paid SNL to make this ad (SNL does paid brand integration in various skits, see Tom Scott's video on product placement for other examples https://www.youtube.com/watch?v=L-x8DYTOv7w). It's a spoof commercial where the product advertised isn't what's being made fun of. The set is unusually authentic to actual Amazon Go stores, down to the "just walk out" logo signage, and the loud and clear message of the ad is that you should stop worrying and trust Amazon. They're lampshading people's distrust of automation, especially in a liberal context of racial equity, and demonstrating that actually Keenan was really silly for thinking a computer would be racist.
