Snowden didn't TELL us anything, he revealed the documents from the perpetrators themselves that tell us everything. What rock have you been under the last few years? You really think the US government wants to arrest Snowden because he is making up lies? Or is it because Snowden STOLE the documents that prove all the assertions? There is ignorance, and then there is willfull ignorance, and I am afraid you are in the latter classification of people.
As far as physical devices, Obviously you are under the assumption that no one in the public sphere uses Intel chips I guess. ALL intel chips on EVERY PC made in the last few years has HARDWARE enabled backdoors for surveillance purposes, the Government has told you so several times now, Intel has also revealed this fact. You Ignore it all you want, but don't try to argue that it isn't happening.
