The failure rate of the butterfly keyboard design is clearly orders of magnitude too high and is the sort of thing people should genuinely lose their jobs over (and perhaps they have). But "orders of magnitude too high" might well mean one or two percent, rather than one or two tenths of a percent; outside the company, I don't think we have any reasonable estimates of the failure rate, just anecdotes. My work laptop has no problem, although its lid is usually closed; my home laptop, a MacBook Escape, also has had no keyswitch problems, although I mostly use an iPad for portable work now. Most of my coworkers have new butterfly-switch keyboards and I don't hear of significant issues; I've talked with a couple Mac IT people at different companies and they haven't experienced huge failure rates, either. This is, again, all anecdotal, though; some people will come back and say "I'm in an eight-person group and three of us had bad keyboards."
