iFixit confirmed that 2016 and 2017 butterfly keyboards are just a little different. They’re replacing with 2017 now and there’s no any data on their actual failure rate except for the fears on Twitter.
Every MacBook I’ve bought for our business (and every MB any of my friends has owned) since 2016 (including the 2017 models) continues to have regular keyboard problems leading to repair.
It’s only a sample size of a couple dozen, but 100% of them have had keyboard problems within 6 months.
