this is like putting a wall in front of, or just beyond the edge of, the slippery slope. the need to make an intentional choice or pause before doing the "getting stuck scrolling" behavior is an opportunity for you to catch yourself and see if that's what you really want.
the platform is designed to capitalize on your slip ups in willpower. you can have great impulse control, but can you have it tirelessly, around the clock? this thing is lurking until you slip, as long as you're on it. attention capture is the goal.
