Let's say for instance that a serious flaw is found in iOS that allows hackers to run malicious code that can destroy your Phone's internal hardware.
Apple puts out a critical patch in response.
You decide not to install this patch or decide you'll get around it to it and your phone is destroyed the following day from a breach.
is Apple held liable because they chose not to force the patch onto your device without your permission or are you responsible because you chose not to install it right away?
Everything can't be black and white.
Same applies to factory recalls of cars. I had a 1986 Nissan 300ZX back in the day and there was a recall because the fuel injectors were leaking gasoline
I took my car in immediately and Nissan replaced the defective injectors. who would be responsible if someone else received the letter, was contacted about the recall but decided to put it off and their car caught on fire and was totalled the following week?
