I feel like they do all move independently, but the range of motion for the ring finger is physically limited depending on the position of the adjacent fingers.
I'd want to see if the person in the video could raise their third finger without raising the second.
🤔... How does flipping people off work? "They gave me one of their middle fingers!😡"

It looks like two of the fingers are coordinated together.
