It is very unfortunate. Snowden is no hero. What he revealed was abhorrent, and should have never occurred. He did right by the world in revealing what he did. But it was reckless. It was sloppy. It was "baby with the bathwater" in such a way that the lives of those in the field were at risk. And then he fucked right off to Russia, where similar and worse activities are undertaken by that government.
So he revealed a terrible fact in an irresponsible way, and then sought asylum in a country which shits on human rights left and right. And this isn't whataboutism, it is an expectation for consistency in morals
