Greenwald was criticized for saying that the USG "should be on it's knees begging every day", a clearly inflammatory thing to say. To act like the criticism is the result of some grand government conspiracy is a bit much.
There are plenty of people outraged by the substance of what has been leaked who also don't like the idea of a) great harm coming to the country or government or legit intelligence operations, or b) a 30 year old person stuck in a Russian airport who has appointed himself the ultimate arbiter of what is leakworthy and what is not, what programs are legal and good and which are illegal and evil.
On another note, the idea of a dead mans switch that harms the government of Country A is probably an attractive target for other governments that want to harm Country A.
