I think the advice was in case the microwave was started accidentally. My parents used to leave a cup of water in the microwave, and they explained it in that way.
I don't think it's gotten any less bad to run an empty microwave, but maybe we've realized starting it accidentally isn't that common, and/or we've gotten complacent.

- hrishi 6y agoModern microwaves also have resettable fuses and protection for the magentron overloading. Not suggesting you run it empty, but it's less of an issue now.
