Macbook m1 2020 screen cracked

i wonder why the macbook air 2020 screen is so fragile and got cracked just because of the dustplug stuck between the gap there. luckily it doesn't affect the display that much. im still using on daily basis with no issues. but there's one time, i put my phone laid to the screen then it goes gitching with pink colour. that was really scary that i thought I'm going to lose my macbook.
