An electronics exporter who violates ITAR and sells electronics abroad is not a secret agent, even if he misrepresented the purchases when he acquired those electronics.
And, how did he get this stuff? By "falsely claiming to be a traffic light manufacturer." Now, think about that for a second. The traffic lights in your neighborhood have "microprocessors which are frequently used in military systems, missile-guidance systems and detonation triggers" ? Well, they may (microprocessors can be put to many uses), but that doesn't mean that the traffic lights in your neighborhood contain secret military hardware. In fact, they certainly do not.
In other words, this guy was convicted of selling export-controlled hardware, which you can buy on the open market, not militarily secret hardware, which you cannot. There is a big difference (not least in that there near no exhaustive list of what is subject to ITAR control, and at times no easy way to determine if something is or is not export restricted), but you wouldn't know it from reading this article.
