Yeah, the UK seems to be the only country that calls gabber or hardcore techno, just "techno". I think this partly came about because in the early days of Skelter's Technodrome you did get dj's like Dave Angel, Colin Favor, Craig Walsh etc playing alongside Producer, Scorpio, Clarkee and so on. As tastes changed the Technodrome name stuck but populated almost entirely with gabber dj's. Same thing with Dreamscape and Dance Planet, they had what they referred to as techno rooms with techno and gabber dj's but that slowly changed to just being gabber dj's.
It's something that seems to persist even now and it's usually a big effort trying to explain to people that techno isn't just 200bpm.
