So the burden of the cost is on the sending party?

In reality the cost is really distributed. The sender hands over the money to the shipping company, but that money comes from the receiver.

And the infrastructure is supported by the community at large.

So when I pay for gigabit internet, and netflix pays their "streaming priority" charge, I get netflix content at gigabit speed.

But when I pay for gigabit internet, and some random startup doesn't pay the ISPs "streaming priority" charge, I get them at some rate limited amount less than what I pay for (gigabit).

That is the problem. The consumer gets screwed, startups get screwed, and the ISPs profit from both consumer and businesses.
