The US Providers like Comcast, Verizon and soon to be others are also directly or indirectly involved in the provision of Streaming Video services.
Their arguments will be used in a similar way by BT, Sky and Virgin, i.e. "We've invested Billions in the provision of all this Broadband Infrastructure for OUR use... why should we allow providers like Netflix, BBC etc. to benefit from our investments without charging them for the provision of the service that enables their businesses??"
Which is IMHO, a reasonable business request on the face of it.
However, the difficulty comes from the fact that this rationale then prevents the next Netflix or similar from rising from the ashes to a position of prominence... e.g. if at their Streaming Launch, Netflix US had to pay Comcast & Verizon the numbers now being charged, then they simply would never have gotten off the ground.
Net Neutrality is an important concept for future growth and choice, but it's got its problems in the real business world.
