Musicians don't break the rules, they make the rules. Music theory is not law; it is an attempt at explanation for the phenomenon of melody and harmony. All three examples in this article have perfectly reasonable explanations in commonly used music theory.
Here are a few... I'm sure there are more explanations. Any thoughts?
1. Chuck Berry - parallel 4ths/5ths/octaves - Was Chuck Berry trying to utilize 4-part voice leading for Johnny B. Goode? Of course not! Pretty much all blues music that predates Chuck Berry uses parallel movement of entire chords. Also pre-dating Chuck Berry and 4 part voice leading - Gregorian chant.
2. David Bowie - C F G A - you expect a modal climb to Am, but you get A major. Slight twist on the age old Picardy 3rd. Lots of ways to look at this.
3. Rage Against The Machine - F tonality with G major harmonization. The article states F has nothing to do with G Major. Both the Phrygian and Locrian modes of F # utilize G major diatonically.
Sometimes going against common music theory rules ends up being exactly what a song needs. It worked for these three songs.
