That's not the right way to look at it. If someone now takes one of these laptops onto a flight and it burns mid-flight that person is now criminally liable. At the very least they will have to pay for the emergency landing etc..
Laptop will explode and burn without caring if their owner knows about it, so I don't know what "fairness" has to do with it here. It's not unreasonable to have a minimum awareness about your own possessions, we don't have to slip into full blown idiocracy.
Yes. Apple sent out notifications to owners of recalled devices. That's why you should register your hardware (trivial in the case of a Mac notebook). In my case I plugged my serial number into the recall site when it was first announced (whilst not logged in to my Apple account) and was told my notebook (a refurb 2015 MBP) wasn't eligible. A couple weeks ago I got an email dictating otherwise.
I've since switched operating systems to Linux and have no intention of getting serviced as there are no authorized service centers in my area unless I get on a plane.
Would I trust anyone else touching my Mac anyway? The answer is no and I plan to buy a Huawei replacement laptop with 5G.
This reads like satire.
