But 2G still has its uses for low-power, low-data applications like embedded devices (IoT).
Anyway, my current beef is all this talk of priorities and so on. What happens in say a very crowded city when the spectrum gets saturated? Neutrality insists on equal time because otherwise people get left out which is unequal treatment of citizens and so on, whereas prioritization takes the capitalist approach, allowing those who can afford it to buy better access by shelling out more money. The MNO's are in the troublesome position of having to find a way to keep as many customers as possible and minimize defections but caught between Scylla and Charybdis in that, no matter what choices they make, they'll lose customers and money.
