The entirely unsupported insinuation that the customer Cisco is describing is the NSA. What's even supposed to be the motivation there? The NSA want weak crypto so they're going to buy a big pile of Ciscos that they'll never use but which will make people think it's secure? There are others, but on its own that should already be a red flag.
The article links a statement from an NSA official that explicitly says the NSA has been asking vendors for this, which seems like fairly strong support to me.
