So if the reasons are neither technical nor financial, what 
gives?

So take a scenario - a provider is present in Rwanda and The 
DRC, and has direct physical infrastructure between these 
two countries.

The provider's customers in both countries multi-home - both 
to the same African ISP who is in both countries as well as 
via a private international circuit to London (probably 
peering at LINX + taking IP Transit from another provider 
there, for arguments' sake). 

So what we're seeing in some cases is that traffic between 
these two customers "could" traverse their common African 
ISP for the lowest latency, but instead, both customers 
deploy routing so that their private circuit to Europe 
carries that traffic instead. So they end up "talking" to 
one another in a very foreign land, across several ponds, 
yet they could simply be talking that much closer, across a 
common border.

One could argue that there is pressure to utilize expensive 
capacity that is in inventory, but the question is whether 
that requirement outweighs the performance gains or cost 
reductions that could be enjoyed by routing consistently and 
effectively.
