My three year old would do the same thing if he was playing in his sandbox and I abruptly picked him up and carried him away from what he was doing though. In my experience managing transitions between activities is one of the most important things. If I let my him watch a video and I tell him "I'm going to turn off the TV when it ends", he just goes back to playing with his toys when it goes off.
Don't get me wrong, I think screen time can definitely be a problem. I just think it mostly comes down to whether or not the screen time is at the expense of something else more constructive.
