Excellent point! In the context of early electronic music (thinking of Varèse), there was a sort of resentment for the fact a composer was limited to working with the sort of sounds that can be "drawn from horse hair and catgut" or by an octave divided in twelve or any instrument other than the composer's imagination. That's how I understood the criticism (which was also voiced in an academic context).
