You also can't say what the intentions of the US government were regarding bringing Snowden back to US soil, and even if that were the case it doesn't seem to mean much especially as it seems the Chicago Police are operating a "black-site" on US soil in contravention of the Constitution.
In fact, I would say the evidence is far stronger for the supposition that Snowden was intended to be "extraordinarily" renditioned than simply and lawfully extradited and your post subjects are ill-argued.
