I'd be completely against passive income that allows a player to simply log off for 6 months and log back into the game with millions or billions of credits simply by "not playing".
The point of the game is to engage with the game, not "disengage" with it.
Introduction of any sort of passive income system should require frequent interaction of some sort- a player would need to log in and do something in order to keep it going.
That said- if passive income were to be introduced somehow, it would need to be severely restricted to amounts far less than what you'd normally earn by completing missions or CG's (in which a player needs to actively play in order to earn credit bonuses) or award simple cosmetic items that do not affect game balance in any way.
