I had 4+ repairs regarding the keyboard and USB C being too loose over time. I have a '17 model. My boyfriend had his keyboard replaced once in his '19 13" macbook pro.
My E key is much brighter than the others after the last repair and they offered to replace my 2017 model with a new 2019 one. I declined the replacement due to the fact that the 19's exhibit the same issue (though its more rare with the newer ones). I also heard of the 16" rumor that was supposed to be released this week which didn't that supposedly has a new keyboard that was used before the butterfly keyboard. I will hold onto my macbook pro until the new one gets released and then demand a replacement. They offered me a 27" Imac instead (Had to be the same price I paid or less), but I declined it because I travel a lot. So I for sure know that they are very lenient in terms of making it up to the customer. I did NOT ask for a refund, and I'm not sure if they would do that, BUT maybe they'd give you a gift card of the price you paid or store credit for future purchase?
Maybe an ex-apple worker can answer this question?
