There's no use lamenting about "I wishes" in this case. It is, what it is.
I can't see ANYWAY that using a standard CAM card versus the present SIM card would make a single $1.00 worth of difference. That's been covered in this thread. They MUST use receivers that are addressable with encryption, locked down, AND that are 100% within their control. That would be a condition of their obtaining programming to broadcast, otherwise they couldn't stay in business long.
So according to what you are saying, using the example of how Cell phones work, you are saying that all cellphones SIM cards should be locked, now days no cellphone is locked, maybe they are carrier locked, but within that carrier you can use any SIM on any cellphone, in my opinion this should be the standard in satellites as well, you should be able to use your SIM and use it in whatever receiver you can afford.
Another suggestion to this new provider is that they should include sports networks for extra price, the reason is because some networks are not available in Directv (Bein Sports) and Dish Network doesn't has Univision Channels so a guy that want satellite service with both channels right now he can't because there's no satellite provider that has both packages.
A third suggestion to me is that as far as I know (correct me if I'm wrong) this new provider should give main channels of ABC, CBS, ABC, Telemundo, Univision and so on, as far as I know those channels have main satellite signal different from the local feed that are send by ATSC.
