You're not talking about the digital adapters now required to watch TV in your house. You're talking about a full digital box (with on demand, cable guide, etc). The digital adapters that TWC provide (in Lexington) only allow the channels 2-99. No premiums. Just channel. They are coax or composite out boxes and are shitty. Why should we be required to have such boxes and pay continuously for them when most TV's today have a digital tuner built in? They cost $0.99 each per month. You can't even turn them off....they stay on 24/7.
Hell, at least get rid of the tuners in the TV's, since we don't need them, and lower the cost and energy usage of the TV.
It's just another perpetual revenue stream for big cable, brought to you by the lobbying firms that they spend millions (if not billions) on.
While I doubt they're all that upset over the additional revenue, that's not the reason why CATV providers have gone this route. The real reason is provisioning.
By going to an all encrypted service, all devices that access the service must be provisioned to receive (and continue to receive) the keys to access the system. This means that turning on service is a few keystrokes, and similarly turning off the service is a few keystrokes. The cable companies no longer have to roll a truck to a dwelling to actually hook up or unhook the service, install'/remove filters, etc.
And admittedly even
that is about money since truck rolls are expensive, but it's not the same outright profiteering. A centrally managed system with fewer truck rolls (read: waiting for service appointments) is better all around.
Is there is a good reason why they don't sell cable cards, so consumers can buy our own?
Long story short: separable security. The idea is that you buy your own box, but the cable company provides the security module. You can't buy the security module since they're meant to be cable company property (so that they can trust they are working correctly). Though the fee is more about the service/provisioning than the cost of the hardware.
