You have no idea if this was as a bigbox store or a local place

Ordinary people are the ones who have to deal with that kind of stupid problem, not the suits in an office park somewhere.

That’s not how you fuck over corporations anyhow, you’re just raising the cost of goods for everyone with no upside. You fuck over the corporations by breaking up monopolies, installing Medicare for All, changing way unions work to make them easier to form and run, make worker co-ops more legally exciting, and require all publicly owned companies to pay out at least 1% of their annual gross profit in dividends each year, among other things.
That’s not what a fail-safe is. A fail-safe is just what it says: the device fails into a safe configuration. In this case, someone has to press a button to quench the magnet, which is not really a failure mode of the machine.
A typical fail-safe is something like a solenoid valve. The valve has a default position when no power is given to the solenoid, and you should design your machine so that the default position is safe (whether that be open or closed). The most likely failure mode is a power loss, so the configuration is said to be fail-safe.
