"technical reasons" should be limited to things like the speed of light, or in this case the necessity to drop packets if the presented load exceeds the output rate of a link for more than the finite buffer can store.

everything else is policy - which means there is a choice. that choice might be heavily driven by economics, or by some kind of business strategy. but its pretty indefensible to say 'the crew in white coats down in the basement told me we just had to do it that way (shrug)'

so in the absence of speed-of-light issues, 'technical reasons' in this case is just a planet-sized loophole.
