Looking some, you're totally right. I'm confused where I picked up the idea that these were called "open"? I think I've seen them written like "G<sub>open</sub>" to indicate that you don't play a 3rd? Calling them "power chords" in a non-rock context sounds off to me, though. Edited the post to call them chords without thirds.
Every guitar player calls them powerchords. I've never heard of another term. Unless OP is referring to double stops. But, those are more of an embellishment, and usually never played on the low E or A string.
It almost always refers to a perfect fifth, optionally with the octave on top. It's a very easy thing to play with two or three fingers, either on guitar or keyboard.

Lots of powerchords in pop too. "powerchord", to me at least, implies that there is a distortion effect somewhere in the signal chain. Powerchords on their own sounds really weak.
