Or, those scenarios just don't make the news as frequent as script kiddie stuff. We only learned about what NSA has been up to because Snowden happened.

If I want to protect against the NSA I'm worried about them using Intel ME, AMD PSP and other black boxes to hack me. I don't worry that much about them sneaking into my data center or house and physically changing my hardware.

The security you lose from having a black box in your CPU is much greater than the security you win by virtue of being (theoretically) protected against unsigned bootloaders and rogue hardware.

I merely provided NSA as an example of how advanced attack vectors might go unnoticed for decades.

This is the opposite lesson to take away from Snowden's revelations. You want more user control, not less.

I agree. I’m just saying that news may not be the best indicator of how common an attack vector is.
