The latter wouldn't surprise me! Lots of people use external keyboards, or just deal with the petty frustration of having to hit certain keys much harder or backspace out the repeats.
It's obviously a serious issue because Apple has created a special program for it. But, it also seems obvious that only some machines are affected, for whatever reason. Maybe some people just type harder than others.
Perhaps it's the dusty office? We are located in a old ship hangar.
What if it’s just climate? Dust and humidity are regionalized. Companies in drier, less dusty, less “sticky” climates might see few to no sticky keyboards.
You might also find different working environments have an effect, is their aircon filtering more dust?
Wait, this laptop portable machine can only be used in environments with filtered air?
This "you're holding it wrong" shit is weird.
In my office we have no issues across about 20 2016 and 2016 models.
I am not even trying to downplay the fact that it's happening a lot; It just seems so strange to read so many people on hacker news talking about extremely high rates of failure in their sample size, when neither myself nor anyone I've talked to has experienced it.
