This is in-line with the the 'under promise and over deliver" mantra I was taught at Apple Retail. Don't make any promises you can't keep, and silently start to fix issues like this. Apple having a hardware fix for their keyboard disasters in this revision is also inline with their repair program they just issued.
Yes, they just issued a repair program. Until precisely 3 weeks ago Apple refused to acknowledge the issue and forced customers to pay for costly repairs on their own dime. This patent was filed in September 2016. Apple was fucking lying through their teeth for a full 22 months and have been caught in that lie.
Frankly I'm amazed there isn't more outrage at this. How could anyone trust them going forward?
