Re: Funding
The "Guardian" is probably giving Snowden a pretty generous stipend. He's still worth a lot of publicity for the Guardian. Besides, if Snowden is indeed so smart, he's probably learning Russian and will doubtless be very useful to the Russians, indefinitely. He's certainly a propaganda coup so far, for all involved, the "Guardian", Gruenwald, and doubtlessly Putin and his staff of writers. Lot's of cash passing to and fro'.
Snowden's persona [the bastard] as far as we've been able - or led to believe - or to divine it from th'media - doesn't seems to lead to alcoholism. Good to be wrong here, tho'.
The real mystery is the brain chemistry which leads these Philbys and these Snowdens to do as they do.
We can't ever know if "it was worth it" for them.
Such a permanent, unyielding price to pay for idealism.
