Re: Nice idea, but...
@Orv,
For that matter, how do we know that it's not really a Decepticon masquerading as a Router/Switch. Or that the plastic isn't some sort of Lazarus plastic that records all the ambient sound in a room.
Maybe the whole thing has been made from entangled particles, and the NSA has its twin installed in their switch-room at their moon base.

There are lots of things to be worried about, this doesn't seem to be one of them. It seems unlikely that the NSA would have the schematics, personnel, replacements, and machines to pull off your proposed chip-change idea. I'm not saying they they can't do it, just that I don't think they are at that level of caring just yet. They have plenty of America's data to keep them gainfully employed for a while.
