In order for a vendor to sell something, he must have a means of excluding those who have not paid. For discrete objects, this is relatively easy. It's pretty easy to restrict a sandwich to the one customer which pays for it. The nature of some products make that more difficult. Water flowing through a pipe requires some sort of metering to charge per unit. For roads you must have controlled access and a means of assessing a toll. If there are alternate roads of reasonable quality connecting the same two points, you must offer some compelling enhancement or you will have no users.
Even with all these possibilities, there are other factors one cannot ignore, often tied to cultures and religions. For example, raising cattle in the lands where certain African tribesmen live requires an extensive guard force. That's because these tribes believe all cows belong to them, a gift from their god. Taking your cows is not stealing, so only the risk of getting killed will keep them from taking the cows. Nothing you say or do will convince them it's wrong. Indeed, they would say you were evil for depriving them of their god's blessings.
The telcos are playing a dangerous game with threats of charging for tiered access to their customers. If they attempt to block Google, holding their customers hostage until Google pays for access across their hardware, they will lose their customers. There are too many alternate routes, and there is no significant enhancement they offer to justify such a thing. That such alternate routes have not yet been highly developed everywhere is merely a matter of convenience. Wireless technology is already quite competitive in many markets, and could easily be more so if the telcos make their services of lesser value to the users.
Beyond the question of mere perceived value is the militant nature of the geek culture. These people believe they own the Net. While many were not living when the Internet was born, they have inherited the culture which created it. Without them, it would almost surely stagnate. Far too many commercial coders share a piece of that culture, and if forced to choose, might revolt in various measures: quitting their jobs, secretly working against their employer, or worse. Those who stay would risk being cut off from the ferment of creativity. Commercial Net operations themselves would be forced to choose, and might easily dump the telcos.
