Promised?
Didn't they also promise that the move to all-digital would not drastically decrease the radius of tolerable viewing? And, OK, maybe they never promised that they wouldn't allow the CableCos to interpret "Must Carry" to mean "Must carry some vaguely plausible rendition of over the air content, but hey, it's OK with us if you downsample 1080p to 480i, compress the crap out of it, and reduce the error correction. The actual resolution, although maybe not compression and error correction, can be an added-cost option", which is of course the way it turned out. (aka a "fee for not spitting in the soup")
