I threw one in the trunk of my car (just in case - I ordered a 4-pack and I had a spare one), and every single time I drive somewhere it chirps loudly when I'm exiting my driveway, making its presence immediately obvious without any delays, and despite my phone being with me in the car.
Let's find out.
I need to replace my current color&laser Brother MFA . The printer still works but software support (on MacOS) has been discontinued. (The profile for CUPS comes with some helper bin/utility, it’s not a plain profile file). Also worth mentioning, the (smaller, not high-yield) color cartridges used to be ~$45 on and now they go for $70.
Some years ago I tried the FM transmitter via GPIO hack for the raspberry pi. The range was surprisingly high, around 100m. First google result. https://linuxhint.com/turn-raspberry-pi-fm-transmitter/
Which outcome is ideal? Which one is morally correct?
(A) the retailer refunds every customer, loses all of their profits and probably goes bankrupt
(B) the retailer is forced to go into massive debt in order to replace everyone's RAM, and may not recover from the debt, and may face legal consequences if they can't replace the RAM
(C) in the first place, the retailer should have been required to have a backup RAM stick for everyone that purchases the RAM, so that they are able to issue replacements if necessary, plus extra in case the replacements themselves are faulty. As a result, RAM prices before this incident were well over 2X the real manufacturing cost, in order to cover this "backup" cost (manufacturing, storage, etc.)
(D) something else?
(This is a much more extreme version of what actually happened, but maybe instructive to think about)
I also fail to see where anyone would expect the current purchase price to be refunded to them instead of the original paid purchase price.
If the regulations require making the customer whole, then I could see an argument for current fair market value, or even just giving nominal interest on the purchase price.
If in your thought experiment, the retailers had a potential risk (requiring fair market value returns/replacement), and they failed to insure themselves from that risk, then they indeed deserve to be forced out of business.
