In fairness, telleyhead said “the lifeless fishbowl“ offered nothing content-wise, not the channel as a whole. 

This is a reasonable point: previous sets contributed to the content in active ways, such as the sandbox or some of the ways the newswall was used. There’s nothing that stands out to me in the current set as integral to the content, which is underlined by the way that shows occasionally use other studios with no change in content. In contrast, it would have been impossible for the presenter to do a live sandbox explainer from the old Millbank set, which was built with its own specific presentation style in mind.

Having sets which are mostly interchangeable and don't actively contribute to the content is a notable change of approach. Pointing that out isn't denigrating anything.

That's exactly how I interpreted it, along with probably anybody who wasn't spoiling for an argument. TV is a visual medium in every single way and this is a presentation forum! 
On that note, good to see Wilfred Frost sent out to the Supreme Court for reaction to the Rwanda decision, made things seem a bit more dynamic and reactive.
