For a company as large as Apple, this seemingly minor issue has sure taken long enough. I'm guessing they're not really investing much R&D to this, it would be impossible to take this long if they threw enough money into it, money that they certainly don't lack.

As someone who is regularly using both Magic keyboard (iMac) and Butterfly keyboard (macbook pro) - butterfly is my favourite by far. Much crispier click point and firmer keys.

Yes it was repaired twice in 3 years (free of charge both times). Would be happy to see it again if Apple can solve reliability problem.

Courage. They must be courageous, courageous enough to not only double down on their mistakes, not triple down, but even quadruple down on bad ideas after seeming to sensibly walk them back. Yes, that is obviously what this shows. Fourth time (reversing the course reversal after the third failure) is the charm!
