Nexus only tried to use them as a scapegoat anyway in my opinion then had no choice but to take it back in house from public pressure, or that was the impression I got. It’s hardly been a glowing operation since then, which suggests the fundamental basics of operating it just aren’t where they’re meant to be, regardless of who is the public face operating it.

There was a raft of funding available from central government, the conditions attached to it meant that the day to day running had to be franchised out. 
DB got it for a couple of years, Nexus got the funding and then the contract ran out. 

That's essentially it. 

I don't think Nexus wanted to do it that way and got out as soon as they could - after getting the funding.
