Doe it matter what time its broadcast, how many people watch it live etc as long as it's made and broadcast? I don't understand why people get so het up about it.
A potential split series: yes, that's a topic worthy of passion.
Broadcast time and live audience: not really. Why do people care about this? Is it just fear of cancellation? Doctor Who fans are very paranoid in that regard.
I'm a little annoyed at the cut from 13 episodes to 12, mainly because we lost a Moffat episode. If the BBC reduces the number of episodes made, as they did by spreading Season 7 over two years, then I will feel consternation over it but as long as we get those episodes I couldn't care less if it's in the spring, summer, autumn, 6PM, 9PM, Saturday, Sunday, Monday. I'll watch it when i want to watch it anyway, like most non couch-potatoes.
