The whole tone of the piece has a kind of "fight the man!" vibe, talking about putting up an "act of resistance" because "MP3's have invaded more and more contemporary listening spaces".

You've got an institutionally-accepted construct designed by white European men for their uses, which inadvertently creates a privileged class that implicitly excludes anything that would've been "other" to those designers.

I wouldn't call it an attack, but I'd call it a weird and not well supported (by what's posted here) social justice angle.
