Wait, so how exactly monetizing at SWTOR works? Guy in charge of it just looks at all avaible stuff, decides "Oh, this would surely sell great in shop! Since players can get it by other means let's slap low price there, and let moeny flow in." and nobody nowhere even checks it, pretty much allowing such cases like this one to happen?
Something like that must have happened - as the dev post said, there was a "miscommunication". You know; business talk for "Big **** Up".
The ship items were not in the cartel Shop on the PTS at any point. Who made the call? We'll never know. Let's just hope they know better next time.
