It's kinda both.
There's nothing that says a word can't have 2 different meanings, but the term "electro" has basically been hijacked. There was - and still is - a specific genre of music called "electro" that is completely different to - and pre-dates - most of the music being discussed in here which is "electro house". It's the equivalent of if there was a type of music called "reggae house" and people dropped the "house" part and just started calling it "reggae". Obviously, people that were into reggae would start saying "WTF??".
This is electro: -
Personally, as a huge fan of electro for 30 years, I think it's important to distinguish between electro and electro house, even if I'm fighting a losing battle on that front.
