Every ISP buys a pipe to one or more major peering points. Either they buy their own pipe, or they buy carriage from another ISP including the large telcos. Those pipes contracts, to the best of my knowledge, are priced on bandwidth, not on application. If a telco tried to change the pricing, the ISPs would switch to any available competition, and there is plenty of competition in this part of the field, and plenty of unlit dark fiber to compete with.

Google probably has its own pipes into the peering points, I would be very surprised if they don’t have pipes into almost all of them. It’s one of the reasons Google is always one of the fastest and most reliable sites. If I can’t ping google, the cause is almost always my own link, not any intermediate link on the net.

The only pipes the carriers own on which there is little competition are the first mile pipes to our homes. It is only on these that they can say, “I am altering the deal. Pray I don’t alter it any further.”
