I've used the 1st gen and the 2nd gen butterfly keyboards. My wife uses the 2nd gen and shes rough AF on her tech.... breadcrumbs, dust, dirt (she uses her mac for ableton on tour).
1st and 2nd gen don't have the membrane.
Still, we have yet to encounter even 1 stuck key. I'm more careful with my tech but I definitely don't baby it...and I've typed a lot of emails and memos on mine... YMMV but I do think this problem, though dreadful, is a little bit overblown.
Most times I read that the issue, if you do get it, can be fixed by tilting the macbook and blowing on it. Not ideal by any means, but not quite 'bricking' that some sentiments might suggest.
The typing experience is ok. Not horrible, you definitely get used to the shallow keys. It's not a negative or a positive for me.
It is however cool right now to rag on Apple.
