"Apple has expanded the existing keyboard repair program for all Apple laptops containing the butterfly design keyboards (including even the brand new MacBook Pro models they just released today, which is interesting, but should be reassuring for those purchasing new Mac laptops)."
What I find most disturbing about this is that the brand. new. models. are included on this 4 year replacement program, indicating that Apple itself doesn't have much faith in whatever changes they made to the now fourth generation butterfly mechanism.
