There's an interesting (albeit tired -- we've been having the same conversation since at least the dawn of the sampler) question in there about where the line between "remixing" and "ripping someone off" gets drawn, but you didn't have to shit all over a subculture and genre of music to pose it.
EDIT: I'll add that there is a pretty direct parallel to be drawn here to the long-running controversy around hip-hop's heavy usage of sampling. Your article, then, read a bit like someone attempting to begin a thoughtful debate about this old "remix culture vs. copyright law" issue with a characterization like "hiphop is a primitive and culturally bankrupt musical 'genre' consisting of a sad excuse for poetry shouted on top of other people's music, and its creators are crooks who appropriate the hard work of others for a less sophisticated audience."
There are people out there that actually believe things like that (maybe even you?), but most of them have the good sense not to say so in public under their true identity. I'd like to think that has something to do with the common decency of not demeaning cultures that one is completely unfamiliar with, and not just fear of appearing to be a racist.
