It's harder to market a product with cap-free times, maybe?
If I was running a network with relatively low capacity at peak but low off-peak usage, I'd offer some sort of incentive for off-peak usage. Verizon not doing this (just like WildBlue has never done this) is there prerogative. HughesNet is the only major provider to offer a cap-free period in the US.
The reason they're not doing it is because they want to profit heartily off of idiots who don't know what a "cap" is. Provide people with the low latency and high bandwidth required to watch videos, and watch the overage profits pour in. They won't even considering just throttling users instead of overcharging them.
Off-peak hours makes perfect sense only if you don't care about maximizing profits at the expense of your customers. Throttling only on congested hours while offering unlimited is also quite possible, especially in these very sparsely populated rural areas.
