Playing the devil's advocate here - Don't all big media companies rely on some form of CDN providers who themselves have some form of deals and agreements with ISPs or Internet exchange. Example - Netflix in India:
A CDN is like having a local power generator in your neighborhood, throttling your Internet is like charging your house more for electricity, because the electrical company prefers your neighbor.

In which case how does this law change anything? And what effect this might have on CDN providers?
