> I’m not entirely sure why it matters that silos of messaging data exist

It doesn't matter until one day, something happens that does make it matter.

Imagine if a centralised model was used and a foreign state managed to sever connections to the internet that was used by that country/central server. It's more resilient to be able to route messages even if the network is under attack. This kind of thinking is behind the original design of the internet although we now seem to have centralised large portions of functionality.
