All company branches set at hub, any reason anyone can think of this would be a good idea?

I just started at a company as a net admin. They use Meraki Cloud, which I've never used before, but every one of the 30 branches set up as a hub, can anyone think of a reason this is a good idea? I've never seen an all hub network.

While I rarely use it, setting all branches to Hub is essentially configuring a Full Mesh AutoVPN topology. It’s one of the Meraki deployment models, and there’s nothing unusual about it.

Perhaps the admin wanted to reduce latency for voice between the branches.
