Can you be a little more specific? Also, re: that article, is there any evidence that there are exploits placed by NSA or GHCQ that could be used by other adversaries? I hear this claim a lot, but haven't seen any evidence...
I don't think there's any evidence that someone has used an NSA backdoor, but, given how widespread exploits are, I wouldn't be surprised.
So yeah they force backdoors.
If you still think you need to defend the NSA, you are not stupid or naive. You are evil.
