Here in the UK almost every KH built or restored in the last 20 years has this exact design of table.. The lectern is of a similar shape. As has been mentioned it is just a practical design for two people sitting facing each other and the audience, nothing sinister.
The tables, lecterns, magazine and literature cupboards are all the same as it is the same company that makes all the woodwork for the KH's and it make sense to use a standard design.
One thing I would say though, we needed new doors on our hall following the old ones being vandalised and it was about half the price to have a local company make them to size rather than the original company supply new ones. As I understand it the company is run by "brothers".....
