On what grounds, exactly?
Self sacrifice in the name of something greater then himself
I guess the Chinese Politburo is, technically, greater than Edward Snowden.
But I'm not sure what he's sacrificed - he seems to have lots of people willing to bankroll exotic travel for him.
A lot of people would enjoy a trip from Hawaii to Hong Kong to Moscow to Havana or Quito or Iceland. Some of it potentially on a G6.
I certainly couldn't afford that elaborate a travel package. I usually fly domestic coach.
