Because, ultimately, it's never been about the phone; it's all about the contract that Verizon / TMobile / AT&T wants to handcuff us to.
Net neutrality "lite" means that the telecoms have extreme incentives to keep us chained to contracts for as long as possible, no matter what advances in technology might make voice and data usage cheaper / bandwidth more efficient, or whatever.
Anyway, I ended up keeping my contractless dumb phone for voice only, and got an Android tablet for anything that would have otherwise persuaded me to want a smart phone. Unfortunately, I ended up needing to buy a data plan for it, which means I'm handcuffed to a contract anyway. But at least the tablet is optimized for "reading" which is what I'd want to do most of, had I a smart phone.
I guess that's where Verizon wins, spending my hard-earned money on lobbying for laws that decrease my power of choice, as a consumer.
