Snowden gave away the crown jewels of intelligence: Sources and methods. If not actual names, he put people in danger.
Can’t disagree but he also exposed what the government is doing to the People - there wasn’t much of a graceful way to do it. An argument can be made on either side of “Keep the People in the dark about government treachery” or “Make the People aware even though it may have some sad costs” - how does one decide when there is no way to both make us aware and protect the assets?
