Screen cracked by itself after 3 months of light use

Same experience like lots of people here. Just bought MacBook Pro less then 3 months ago, only used it the last month and was very careful, I am sure I didn’t drop it, just opened one morning and there’s a line across the monitor and it doesn’t turn on. There’s no visible damage or cracks anywhere, I was told it’s not covered by warranty because it’s considered as damage. Thank goodness my credit card purchase protection was able to cover 500$ out of 1400$ I spent on this computer. I won’t be fixing the screen after seeing it cracked again for a lot of people. It’s insane that the screen repair costs like almost new computer, and even more insane they don’t make quality screens to begin with.
