I must dispute your assertion. Mine is a free to air decoder and NTV is live. Victor has also confirmed on his end the channels are available on free to air. Citizen is not on, but I would be hesitant to jump on the claim that CA has switched it off. It could be a problem with their signal because I have experienced trouble with that channel even before today.
It's been pulled off the air from free to air. If you have a decoder you still have NTV though Citizen is offline. That said I shared screenshots of live reporting so know I not making this up.
