This happened to me. Twice. I bought a 16" mbp when it was released because the keyboard of the previous mbp gave me carpal tunnel. I immediately added a camera cover like I always had done on macs. My screen stopped working a few days later, but mbp still worked on my external monitor. I took it in and they replaced the display for free via applecare.

Once I got my mbp back, I added the camera cover again (stupidly). The next day I opened my mbp, and had a line down the center of my screen. That is when I realized what had happened. I then told Apple exactly what I think happened. And to their credit, the replaced it (again) for free.

Over the next weeks, I received 3 different calls from Apple staff, with seemingly increased responsibilities. They all asked detailed questions investigating what I thought happened and in what sequence.

I am not surprised to see this support article.
