i have long suspected that BGP routes can be altered on-demand to push domestic traffic outside national borders and justify its recording and use by intelligence services.
it is entertaining to see this done in the wild.

If you can announce a relatively concise prefix of traffic you know you want and nobody notices it's pretty easy for this to go unnoticed for a period of time. As the prefix gets smaller that's harder to control however (since more specific routes will generally be installed in the routing table over less specific).
That being said it shouldn't be trivial to announce networks you don't own. This is where the people process oft breaks down.
