Apple builds obsolescence into their products on purpose.
If you'd bought a PC, a faulty screen would be easily replaceable. I had to replace my laptop screen myself several years ago, and with a $60 part and ten minutes on youtube, it was an easy repair.
Hmm. I'm still using a 2014 iMac, as its 27" 5k screen still very good for coding (with added memory). Sometimes develops a bunch of thin vertical lines, which come and go maybe dependent on temperature, but hasn't changed for for ten years and i can live with those. Just wish they'd continue providing security updates for it.
Yeah, depending on how widespread this is, it's probably worse than staingate.
I bought a 2014 MacBook Pro earlier this year, I got a good deal on it partly because it's got severe delamination issues. With dark mode, it doesn't really bother me enough to spend several hours with a bottle of Listerine to fix it yet.
