Since I got my swami hat on, I also predict that more reasonable pricing for tethering and/or the addition of home broadband replacement pricing will come out afterwards due to market forces and user demand.
So let me get this straight... You think once Verizon successfully locks everyone else out of providing tethering on their network, they are going to lower their prices for everyone?
Nope, not happening. In fact, its more likely they come out with stricter guidelines, harsher penalties, and a higher baseline cost for the services. You speak of market forces and user demand. Those are meaningless if they are the only ones providing that service on their network. If they have no competition, why would they set a competitive price? If anything, they'll set a monopolistic price and you can take it or leave it.
This is like thinking that once OPEC seals control over the entire world's stock of oil, they'll lower prices due to market forces.
