It sounds like the point you're making is that manufacturers taking liability will make all of this unaffordable for normal people, similar to how medicine has become unaffordable?
I don't think that's actually your point, but it sort of sounds like it.
There are probably elements of that but my read of the post I replied to was "why on earth would you expect manufacturers of equipment to accept liability for misuse?" (I actually agree about misuse, but malfunction is not the same.)
And "in the context of something that is designed to save lives"... well, absolutely, many manufacturers do and will and even "have to".
I don't think that's actually your point, but it sort of sounds like it.
