Nothing really. I think I understand perfectly why he did what he did.
And despite all the revelations made through news agencies (which are already starting to wrap it up as "old news") NOTHING has changed in any material way. In fact it's gotten far worse now that those responsible are doubling down, openly covering for each other, and saying "Too damn bad! Sue me!" while flipping the bird in response to each subsequent revelation.
If nobody cares, Snowden wasted his time. And nuked much of what passes for a normal life.
On second thought...I do have one question:
How's the food?
