Negative way? How come? I love drone music. And there are many people who do. Including absolutely minimalistic stuff.
I do love both genres, but droning might be more connected to more brutal sounds like sunnO))) and the like, while the two songs of yours I heard so far could maybe benefit from being termed ambient. I'm guessing that's what he's getting at. Two sides of the same coin though, I don't see anything wrong with calling it droning, when that's exactly what it is :)
