The snowden leak was huge and reverberated for weeks. There were lots of followups. However at the time it was the more sexy things like tapping google's fibre and backdoors in cisco's kits that were more interesting. This is because the public could understand those things and therefore it sold papers. The difference between "cisco, dell and many other leading manufacturers shipped backdoors in their kit" and "cavium the small provider you've not really heard of" is large. Most people reading the snowden stuff will have assumed that the NSA had put in backdoors to most things.
