I should've posted this on the first day of April, but I forgot about it.
As we know, the trademark Unix isn't solely for the operating systems, other products are allowed to use that trademark if they're of different category and won't cause ambiguity.
UNIX Electronics (a Korean company manufacturing home appliances, such as hair dryers) is one such company, so what should we do when we encounter people asking Unix questions that isn't about the operating systems?
