this whole issue is a phoney problem.
bandwidth hogs like youtube
expect to get the same priority as email.
but youtube needs 100000X as much bandwidth.
The issue isn’t Youtube versus email, it is YouTube versus Breitbart. Google can pay whatever extortion Comcast or Verizon demands to carry Youtube, but Comcast and Verizon could probably squeeze Breitbart or RedState or any other uppity small company out of business given the chance.
