I think the e-waste angle is mostly unrelated.
Is it though? I was able to replace a broken Macbook screen a couple of generations ago. It was hard and took a while, but I managed. I'm very sure I would not be able to do this given this kind of screen.
I guess we'll see when the first tear-down comes out. I wouldn't be surprised to find out that the only way to fix the screen is to replace it together with the webcam.
