He really meant it
When he said we'd go so far.

Before becoming renegade, he was the most feared Federal Space Navy officer. Feared not by enemies, but by his... less, shall we say, honourable, brothers-in-arms. How bad was he? Well, he wasn't nicknamed "Iron Arm" for no reason. And when he said, "I'm tired of you guys making visual puns on me", the other nickname rose; one said in some sinister manner; one that became most infamous in whole Federal Space Navy; "The Commissar".

Later reports from free merchants and corporate navy say that he may be located on so-called "Station 42", which he commandeers. Station is located in deep space and changes its location on regular basis, though the new location is completely random.

Agent Steele, would you PLEASE stop bothering me with your fairy tales about space stations in the middle of nowhere? Intel Corps have a lot of job to be done, chasing myths told by drunks in spaceports is NOT part of it.
