"Apple has faced public scrutiny and many, many complaints". please define "many, many": 6, 100, 1000, 10% of owners? Seems more like a made up issue by a few loud influencers, maybe even paid influencers, than a real one. I'd say it was not many, many unless the defect rate exceeded say 2% of owners.
I don't know about anybody else, but out of the two butterfly MBPs I use, both obtained at about the same time, and both carried in the same camera bag at all times, only one of them is fine after about two years. The other had a couple of keys that started malfunctioning after about three months, and at this point, has five or six key caps that quite literally fall off if I turn the machine upside down. I've never had a Mac keyboard failure of any kind in 25 years of using them prior to this one, so to say that this is alarming is something of an understatement.
BTW, a failure rate of even 0.1% of hardware is typically a recall-level event when you're building things in the quantities that Apple does. I'd be willing to bet that this keyboard's failure rate is way, way higher than that. In fact, one recent study suggested that the number
might be as high as 30%, which from any less beloved company would be a career-ending failure, if not a company-ending failure.
My guess, based on a non-random sampling of people I know who own/use them, would be probably more on the order of 10%. Either way, this keyboard is an absolute disaster, and I'm being generous with that wording.
The class action lawyers working on this should not accept any warranty extension that does not include replacement of the keyboard with a redesigned model. It should be relatively easy for Apple to provide updated top-cases based on the 16" keyboard, with connector cables designed to attach to each of the previous 15" models' logic boards, and nothing less than that complete solution is, IMO, an acceptable outcome from this lawsuit.
