What's old is new. It only took Apple 3.5 years to own up to their previous "staingate" display disaster: https://www.macrumors.com/2015/10/17/apple-mbp-ar-coating-qu...
My system developed the problem, I was about 2 years out of the warranty, and by the time I heard of the double-secret recall, it had ended.
They didn't even provide for all the machines affected, just a subset of models.
An apple store rep or genius will lie to your face that there's nothing they can do about a particular issue, but come back and ask a different employee with the magic words for the secret recall and it gets taken care of.
It's fucking bullshit. Apple is rolling in piles of cash and they pull this shit to pinch a few pennies here and there.
I've honestly had much better customer service experiences with just about any other OEM.
