I think I recall DB or one of the devs actually saying at one point they would like everyone to play in open. But that's really not the same as saying everyone should or that it's the right way.
They could make it open or nothing - they could do whatever they liked.
But they don't because they know their customer base well and they understand that technical limitations actually prevent some people from playing in open.
