The soulless look is a combination of sparse studio in an irrelevant location and automated cameras, controlled by the automated Overdrive broadcast system. If you want to know why Sky News has gone from a powerhouse in the 90's to a regional rip & read service today watch the regional US stations use it. When you have a soulless control-room with one person, you can't expect the presenters to show any hunger delivering the pre-determined template content. And you certainly can't expect one person to be across all of the news developments and video feeds without making on-air mistakes.

As someone who has worked in an Overdrive control room on a regional US station, I'm not sure what you're saying is accurate. I highly doubt Sky's control room today looks like the one in that top video, or that only one person is in Sky's control room. Our control room had three people in it — a producer, a director/TMP, and a master control operator, since our master control was hubbed. This was for a show that was ostensibly a quick, hard-hitting morning show with 2-3 live reports each hour. On some of our off-peak hours (midday, late night, and weekends), the producer *is* the anchor, so then there's only two people in the control room, but those shows are usually not more than 30 minutes and had at most one live reporter. In some really small stations or stations where master control isn't hubbed, then yes, there may be only one person in the booth. But what I'm trying to say is that our shows were still pretty simple compared to what's in an hour of Sky News today, where Sky still has a lot more live elements than we did and produces far more hours of live news than almost any local TV station in the US does. So sure, there might be more tech/directors in a Sky control room, and there's undoubtedly going to be at least 1-2 more producers/associate producers in there to coordinate all the live feeds, talkback with all the talent and photogs, and changes to the rundown mid-show. And there's still going to be an executive producer outside the control room overseeing everything — our anchors were our de facto EPs, which is pretty common for a small market in the US.
Also, everything is automated now, including the BBC. Almost everything. It's not unique to Sky. It's sad to see people lose their jobs, but it's a reality that this is the direction this industry has marching toward for the last three decades. Actual viewers don't notice, and for the talent, as long as there's still a producer on IFB bringing everything together, then the talent isn't going to show "any less hunger" to deliver the news, whatever that means.
