Earlier quoted context omitted.
Are you sure you don't have cause and effect reversed? Could it be the case that those companies donate to politicians because those politicians views naturally align with their own?
Nobody in Congress had a view on net neutrality until they were paid to. Because it's a largely invented issue between those groups of corporations. ISPs want to charge tech companies more for the traffic they generate, and tech companies don't want to pay it. Those companies were already donating to politicians which align with their own views... but primarily because of their views on other topics.
The different internet providers have peering agreements. If traffic isn't the same between the two peers, they pay the difference.
Simplified. If Netflix's service provider is Verizon and they have a peering agreement with Comcast and Netflix traffic is causing peering to become out of balance between Comcast and Verizon. Verizon pays Comcast and Verizon charges Netflix more. No one is getting a free ride.
