Quite a lot of bollocks in there.
Who are the acts which we wouldn't know exist if they hadn't been pirated, because the majors didn't make them publicly available? How did that work, did someone sneak into their house and record them, then stick them on KaZaa?
It doesn't matter who the record companies push. You buy who you like the sound of. You can easily find people playing interesting music if you look around a little in legal ways.
