It's not the water that's the issue generally - it's the minerals in the water.
The article author got lucky this time - when electronics die from water contact, it's usually the minerals bridging connections and creating shorts. Letting the device dry does not remove those shorts. Some places have such hard water (lots of minerals) that evaporated water leaves calcium, limestone and other deposits on the surface of everything it's touched.
Does that mean doing it once will always cause an issue? Of course not... but repeatedly doing this, and/or becoming used to washing electronics in the dishwasher is a recipe to ruin them in the long term.
I would not personally want to play games with a toaster that can be replaced for $20 at your local Walmart...
