Greenwald worked for The Guardian for the initial release, and works for The Intercept now. The Guardian, although somewhat ad-supported, doesn't appear to be quite as dependent as most US papers: https://en.wikipedia.org/wiki/The_Guardian#Ownership_and_fin.... The Intercept is definitely weirder than that: https://en.wikipedia.org/wiki/The_Intercept

With respect to The Intercept, I submit that you're technically correct (their motivations and Snowden's aren't identical), but that Snowden's motivations are probably closer to The Intercept's staff than they would be to any other news outlet, even NPR.
