Hogosha have been the middle man on business between Kusari and the Corsairs, in the same way that GC is the partner for the Outcasts in Kusari.
The changes in the laws legalizing the artifact trade in Kusari have on one hand have turned the hogosha dealings into legitimate business (coupled with hogosha "no piracy in Kusari rule", and Corsair law "no piracy in Kusari space" rule). On the other hand, it also opened the gamma trade to the other Kusari corporations, meaning that the Samura with their active members have taken the main role in the relations, sidestepping the Hogosha (like the hogosha did to the GMG, OH the IRONY!!).
Of course many hogosha would resent Samura messing with their dealings and profits, but Samura can't do anything about it (read the ID). They could get friendlier with Kishiro, but Kishiro aren't as versatile as Samura in shady dealings, and they're too close to GMG too.
Hogosha can use their rather lack of criminal history to infiltrate Rheinland and Liberty and Gallia (and edges of Bretonia). The main problem of this is the well established presence of the Junkers, and the lack of Corsair aligned unlawful factions in Liberty.
