Unless AT&T has changed how their hotspot entitlement works in 4.4.3+ I don't see any problems with anything you've done to your device. If its possible and not a pain I'd say flash back to 4.4.2 if you really need to tether. Then we can wait until 4.4.4 is out on AT&T and see if other users are having the same issues.
I visited with AT&T the other day and it may be AT&T. Their tech support staff isn't overly knowledgeable, but basically their explanation is I have a "non-AT&T phone" since it is a Dev Edition bought from Motorola which messes up provisioning on their network. Since USB tethering works, I'm just going to sit tight until 4.4.4 rolls out and see what happens but thanks so much for taking the time to respond.
