It seems to me that Indians on average cared a lot more about independence than Americans on average care about freedom from the government spying on them, so I am not sure that Snowden coming back to America would really change much. I think that Snowden has already done more for Americans' freedom than almost anyone else in the world has done and I think that it is understandable if he would rather continue to live outside America rather than risk himself for the hope of changing things further. His initial revelations faded from the media spotlight within months. Even the potentially explosive Epstein case and Epstein's death faded from the media spotlight within months. It is hard for me to imagine that Snowden coming back to America would be likely to accomplish much more than what his initial revelations accomplished. Plus, it is possible that his continued freedom will actually inspire more future activists than him losing it would.
