All said and done, the problem with butterfly keyboards is the reliability. We don't associate 'unreliability' with Apple devices and screwing up on the keyboard is a big screwup because for those whom it won't work, it just makes your laptop unusable. Hence the justified pushback. That did not happen with removal of CD drive, adding USB C only ports, removing magsafe. All these cause some painful transitions, they did not make your laptop unusable. FWIW, I have 2018 MBP and so far the keyboard has worked fine, though I don't enjoy the lack of tactile feedback; I can see the perspective of those who bought it and the butterfly became kaput.
