Bin Laden did, which was probably why he was so difficult to track down. My understanding of the situation (correct me if I'm wrong) was that the rest of Al Qaeda and their affiliates were not as careful with their security. He might never be caught using an internet connection or cell phone, but it wouldn't necessarily matter if 90% of his organization did. Nuances would matter quite a bit, too. Bin Laden stopped using his satellite phone after he suspected that the NSA could listen. But what about the satellite phone made it insecure? The fact that uses satellites? Would a cell phone be susceptible? GSM? CDMA? Only Motorolas? Are land lines secure? What if they're encrypted? What encryption schemes are secure? I don't have the documents off hand, either (sorry), but from what I've heard their overall security was pretty lousy - I remember reading that they were doing things like rolling their own encryption.
