Earlier quoted context omitted.
and it only took them 4 years to acknowledge the issue?
Probably they acknowledged it sooner, but only after 4 years, they are offering free repairs and compensations.
My 2011 MBP, which was out of AppleCare, basically died a few months before they announced the repair program. I was very lucky I didn't sell mine for parts at a loss -- I seriously considered it.
I still lost a little bit of money because I basically gave away the RAM upgrade I bought for it, as I had no idea when or if they'd even offer a repair program.
