This is a good point, which I acknowledge. Maybe I've been lucky with my keyboard. But while you point this out, I think most folks complaining about the keyboard are not acknowledging the other side - that it may not be as important as they think it is either. Hence my original comment indicating my own opinion.
> For students, teachers, scientists .. any one that uses a keyboard frequently... it would have to be real hard to write a paper with keys that fail or keys that start repeating constantly.
For what it's worth, I wrote a ~170 page paper (in LaTeX) on a 2016 MacBook Pro. I cared a lot more about screen real estate than the keyboard, so I added a few monitors. All anyone seems to be able to provide is an exchange of anecdotal evidence for or against the keyboard. If there's a real issue I'm not defending it. But I am saying it might not be worth it for Apple to fix it depending on incidence rate, and it might not be as prevalent as the tech blogging/journalism sphere would have us believe.
